Frank J. Kelley, Attorney General, Thomas L. Casey, Solicitor General, Ray W. Cardew, Jr. and Morrison Zack, Assistant Attorneys General, Detroit, for the Second Injury Fund.
LEVIN, Justice.
Victoria J. Lawrence was injured while working for Prompt Answering/DeBonte Electric. Her injury prevented her from continuing her employment with Prompt, but did not prevent her from continuing her dual employment at Plainfield Drive-In where, at the time of the injury, she had part-time seasonal employment in the sedentary job of selling movie tickets.
The questions presented are whether
 the wages Lawrence earned at Plainfield were properly included by the magistrate and the WCAB in computing Lawrence's "average weekly wage" for the purpose of determining the benefits payable to her;
 Lawrence may have lost the earning capacity represented by the wages she earned at Plainfield although she continued to be there employed immediately after she was injured at Prompt; and
 the Second Injury Fund may be subject to liability for a portion of the benefits payable to Lawrence in respect to the wages at Prompt even if it is determined that Lawrence retains earning capacity in respect to her wages at Plainfield.
We agree with the Court of Appeals,[1] the Worker's Compensation Appeal Board, and the refereewho all ruled that the 1980 amendments[2] of §§ 371[3] and 372[4] of the Worker's Disability Compensation Act,[5] providing that the average weekly wage means the weekly wage earned by the worker at the time of injury "in all employment,"[6] mean both the wages earned in the employment (at Prompt) in which the worker was disabled and in an employment in which (at Plainfield) she was not disabledthat the WCAB properly included the wages Lawrence earned in all employments in computing her average weekly wage.
Neither the magistrate nor the WCAB made findings concerning Lawrence's ability to earn the wages she received from Plainfield. We conclude that whether she lost her entire "earning capacity" remains a question of fact for the magistrate.
The WCAB found that the Second Injury Fund would be liable for a portion of the benefits paid to Lawrence, even if that portion is being paid to replace wages lost from the employment at Prompt in which she was injured. We disagree, and conclude that in such a case the Second Injury Fund is not subject to liability for the payment of any benefits replacing the wages Lawrence earned during her employment, at Prompt, in which she was injured.

I
The WCAB found that Lawrence was partially disabled by June 15, 1985, from her employment with Prompt as a result of a *157 knee injury,[7] and entered an open award of benefits until the further order of the WCAB. The WCAB ordered that, in computing the weekly compensation benefit, Lawrence's average weekly wage was to be determined by including both wages from her employment with Prompt, which she could not continue because of her disability, and wages from her employment with Plainfield, which she had been able to continue. The order provided that Prompt could take credit, pursuant to the formula contained in subsection 361(1) of the act,[8] against the weekly benefits for any wages Lawrence had "actually been able to earn" after June 15, 1985.
The WCAB order further provided that the Second Injury Fund must reimburse Prompt for a share of the benefits proportionate to the ratio Lawrence's preinjury wages at Plainfield bear to her total average weekly wage, unless Lawrence's earnings from Prompt comprised more than eighty percent of her combined earnings from Prompt and Plainfield, in which event the Second Injury Fund would not be required to provide any reimbursement to Prompt.[9] The Court of Appeals affirmed.

II
This Court granted the application of the Second Injury Fund for leave to appeal. Lawrence had responded to the application with a motion to dismiss as moot. The order granting leave to appeal states that the motion "remains pending. The parties are directed to include mootness in the issues to be briefed."[10]
Lawrence contends that the issues are moot, and the appeal should be dismissed because the sole issue presented is whether the Second Injury Fund is required to reimburse Prompt under the circumstance that Lawrence was able, after injury, to continue working for Plainfield. Lawrence asserts that computing Lawrence's average weekly wage by including her earnings from Plainfield, in the manner required by the WCAB, results in Prompt's share being eighty-three percent, with the further result that Prompt is required to pay the entire benefit and the Second Injury Fund nothing. Subsection 372(1) (see n 9 for text) provides that if the employment that caused the personal injury provided more than eighty percent of the injured employee's average weekly wages at the time of the injury, the employer is liable for all the weekly benefits. Lawrence points *158 out that Prompt has not appeared in this Court, and asserts that Prompt does not seek reimbursement from the fund.
The Second Injury Fund contends that the issue may not be moot, and that it may, under the Court of Appeals opinion, have reimbursement liability to Prompt. It further contends that even if an issue is moot, this Court may address the issue if it is of public significance and is likely to recur, yet may evade judicial review, citing In re Midland Publishing Co., Inc., 420 Mich. 148, 151-152, n. 2, 362 N.W.2d 580 (1984), and Pearson v. Macomb Co. Election Comm., 199 Mich.App. 170, 171, 500 N.W.2d 746 (1993).
This Court has decided to address this appeal on the merits.

III
The Second Injury Fund states that the issue is the validity of imposing reimbursement liability on the fund pursuant to § 372 "for any portion of plaintiff's weekly workers' compensation benefit given her disability from the job [with Prompt] in which she was injured but not from her concurrent employment" with Plainfield.
The fund acknowledges that Lawrence has been found to be disabled, but argues that her "disability has been finally determined to extend only to her employment by Prompt, and not to her concurrent employment." It asserts that Lawrence has suffered no wage loss from her concurrent employment, and therefore "Prompt's obligation to pay weekly benefits is based solely upon [Lawrence's] wage loss, from Prompt." It argues that a worker is entitled to benefits only where there has been a loss of wage-earning capacity, citing statutory definitions of "disability"[11] and this Court's decisions in Sobotka v. Chrysler Corp. (After Remand), 447 Mich. 1, 523 N.W.2d 454 (1994), and Michales v. Morton Salt Co., 450 Mich. 479, 538 N.W.2d 11 (1995), discussing "disability" and "wage loss."
The fund further contends that the purpose of the 1980 amendments were solely to address the inequity of the result of this Court's decision in Buehler v. Univ. of Michigan, 277 Mich. 648, 270 N.W. 171 (1936), in which a worker was injured while working a part-time job and was disabled thereby from both the part-time job and a full-time job, and yet was held to be entitled to benefits only on the basis of her earnings from the part-time job. The fund asserts that the Legislature did not intend that the 1980 amendments would apply except where, as in Buehler, the worker was disabled from all dual employment.
The parties agree that Lawrence was disabledthat she suffered a work-related injury in the course of her employment that resulted in some loss of wage earning capacity. The parties also agree that Lawrence was not disabled from her employment at Plainfield.
"Disability" and "wage earning capacity," as those terms are used in the act, are interrelated but different concepts. A worker is not entitled to benefits unless he is "disabled." "Wage earning capacity," in addition to other possible applications, plays a specific role in determining the amount of benefits in a partial disability case.
Because Lawrence retained some ability to work, Lawrence was properly determined by the magistrate and the WCAB to be partially disabled. The amount of her benefits is, accordingly, to be determined under § 361. Pursuant to § 361, Lawrence is entitled to her preinjury "average weekly wage" less the wages she is "able to earn" after the injury.

A
The "average weekly wage" is to be determined under subsection 371(2) of the WDCA, which provides:
As used in this act, "average weekly wage" means the weekly wage earned by the employee at the time of the employee's injury in all employment, inclusive of overtime, premium pay, and the cost of living *159 adjustment, and exclusive of any fringe or other benefits which continue during the disability.
As the fund contends, this section was amended in 1980 to overrule the result in Buehler by providing in subsection 371(2), that the "`average weekly wage' means the weekly wage earned by the employee at the time of the employee's injury in all employment."[12] (Emphasis added.)
Neither the definition of "disability" nor judicial decisions opining concerning what constitutes "wage loss" are pertinent in determining the "average weekly wage" once it is determined, as it was here, that the worker is disabled. When disability has been determined, the computation of the average weekly wage is statutorily prescribed in § 371 and does not involve a further determination or redetermination of the extent of the worker's disability in dual employment. In enacting that the "average weekly wage" means weekly wages earned by the worker at the time of his injury "in all employment," the Legislature did not distinguish between dual employment in which the worker was injured or disabled and dual employment in which he was not injured or disabled.
The WCAB was therefore correct in concluding that Lawrence's wages from both Prompt and Plainfield should be included in her "average weekly wage."

B
The second phase of the calculation of benefits for a partially disabled worker requires a determination of the wages that Lawrence was "able to earn" after the injury. This Court has said:
[W]age earning capacity ... is a complex of fact issues which are concerned with the nature of the work performed and the continuing availability of work of that kind, and the nature and extent of the disability and the wages earned. [Pulley v. Detroit Engineering & Machine Co., 378 Mich. 418, 423, 145 N.W.2d 40 (1966); Sobotka v. Chrysler Corp. (After Remand), 447 Mich. 1, 22, 523 N.W.2d 454 (1994).]
The fund and the author of the dissenting opinion would make wages actually earned following the injury the sole determinant of earning capacity. This Court has rejected this approach:
[I]f the bare elements of proof of what the employee was paid were construed as establishing his "earning capacity" the whole purpose of the act would be vitiated. [Pulley at 423,145 N.W.2d 40.]
Wages alone can overvalue an employee's worth in the labor market if they are temporary and inflated, or undervalue it if he is employed at work below his skill level. The full severity of an injury may not reveal itself immediately after it occurs, or an employee may struggle along with the injury before determining it is impossible to go on.
Potential ability to work, if uncoupled with an actual opportunity to exploit that potential, leaves the employee unable to earn wages. In this case, the range of activities Lawrence is physically able to perform has been severely limited. Only a small fraction of available jobs will be as suitable for her as was her sedentary work at Plainfield. Thus, although Lawrence, immediately after the injury, actually continued to earn wages at her part-time summer job at Plainfield, it does not follow that she was "able to earn" replacement wages, as that term is used in the act.
While Lawrence continued to be employed during the summer of 1985 in her part-time sedentary job, her injury incapacitated her from other employment requiring walking, *160 standing, and bending. Lawrence's job with Plainfield was a part-time summer job which, in all events, came to an end two years later when this drive-in, like most drive-ins, closed permanently. The record indicates that Lawrence was diligent in seeking other employment, with the result that Prompt was entitled to substantial credits for wages earned by her in such other employment.
The purpose of the 1980 amendment was to assure that a disabled worker who, like Lawrence, had been engaged in dual employment before the injury, would be entitled, as set forth in § 361, to benefits equal to eighty percent of the difference between her after-tax average weekly wage from dual employment before the personal injury and the after-tax average weekly wage that she is "able to earn" after the personal injury.[13]
The WCAB order returned this case to the magistrate to determine the wages Lawrence "has actually been able to earn" since the injury. Although Prompt would be entitled, pursuant to § 361, to a reduction of its liability for any wages Lawrence actually earned, the WCAB order does not require the magistrate to determine whether Lawrence retains any residual earning capacity, which also would reduce the amount of the award, but not Prompt's liability.
In sum, the wages Lawrence is "able to earn" is a question of fact, to be resolved by the magistrate after considering the full range of factors set forth above. The amount of wages Lawrence is able to earn is neither constrained nor controlled by the wages she actually earned following the injury.

IV
The final issue is the apportionment of liability for benefits. Apportionment in a dual employment situation is controlled by subsection 372(1)(b), which provides:
If the employment which caused the personal injury or death provided 80% or less of the employee's average weekly wage at the time of the personal injury or death, the insurer or self-insurer is liable for that portion of the employee's weekly benefits as bears the same ratio to his or her total weekly benefits as the average weekly wage from the employment which caused the personal injury or death bears to his or her total weekly wages. The second injury fund is separately but dependently liable for the remainder of the weekly benefits.
The parties agree that Prompt is required to pay the entire amount of the award if the portion of her average weekly wage resulting from her employment with Prompt is more than eighty percent of the average weekly wage computed by including Lawrence's wages from both employments.
The WCAB appears to have construed § 372 to mean that the Second Injury Fund should bear some portion of the liability for benefits payable to Lawrence, even if the magistrate determines that she has not lost any earning capacity in respect to the wages received from Plainfield:
Calculation of the Fund's obligation to reimburse Prompt Answering requires the calculation of the employer's percentage and the Fund is "separately but dependently liable for the remainder." The numerator of the ratio is "the average weekly wage from the employment which caused the personal injury".... The denominator is plaintiff's "total weekly wages" which is to be determined according to [§ 371], as we have set forth above. This ratio is the employer's percentage and the remainder (or, mathematically, 1 minus the employer's percentage) is the Fund's percentage. [WCAB op. p. 19.]
This construction of the act exposes the fund to liability for benefits being paid solely to compensate Lawrence for the incapacity to earn the wages paid by Prompt.
The legislative history of subsection 372(1)(b) is clear that the Second Injury Fund is liable only if the employee experiences wage loss from employment other than that in which the injury occurs, and that employment contributed more than one-fifth of the employee's average weekly wage.[14]
*161 Section 371 was enacted to include "all employments" in an effort to remedy the perceived injustice of this Court's decision in Buehler. At the same time, the Legislature amended § 372 to apportion liability between the injury-employer and the Second Injury Fund. Such apportionment places responsibility on the injury-employer for the wages that were lost while the worker was in its employ, yet protects that employer from loss for hiring a worker with concurrent employment.
The approach stated by the WCAB threatens to distort the balance struck by the Legislature. Because the WCAB formula would apportion liability between Prompt and the fund in proportion to the wages paid by Prompt and Plainfield before the injury, without regard to whether Lawrence lost earning capacity in respect to wages received from Plainfield, the WCAB potentially released Prompt from the full burden of compensation that the Legislature intended that it, and it alone, should bear. Accordingly, if the magistrate determines that Lawrence did not lose her capacity to earn the wages she earned at Plainfield, Prompt and Prompt alone must bear the full responsibility for paying benefits and compensating Lawrence.
We construe § 372 to require the employer under whom the injury occurred to pay the portion of the benefits equal to the ratio that the wages paid by the injury-employer for which benefits are payable bears to the total wages for which benefits are payable. Thus, the fund is only subject to liability for benefits in respect to the wage-earning capacity lost at the concurrent employment.
The Second Injury Fund's responsibility will arise only if Prompt's contribution to the average weekly wage, computed by including the wages from both employments, is determined to have been less than eighty percent. In that case, Prompt will be solely responsible for shouldering the burden of the benefits attributable to its share of the wages for which Lawrence is receiving benefits, but is entitled to reimbursement from the fund for any additional benefits, because, in the language of the statute, "the Second Injury Fund is separately but dependently liable for the remainder of the weekly benefits."[15]
Affirmed in part, reversed in part, and remanded to the magistrate.
BRICKLEY, C.J., and MICHAEL CAVANAGH, J., concurred with LEVIN, J.
BOYLE, Justice (concurring in part).
I agree with parts I, II, III(A), and IV of the lead opinion. Given that the parties have not presented arguments involving the relationship between "disability," "earning capacity," and wages the employee is "able to earn," I express no opinion regarding the remainder of part III of the lead opinion. The parties do not dispute application of § 361,[1] and I therefore agree that a remand to the magistrate for application of § 361 is proper.
MALLETT, J., concurred with BOYLE, J.
WEAVER, Justice (concurring in part and dissenting in part).
I concur with the majority holding that the Second Injury Fund is only liable under § 372, the apportionment provision of the Worker's Disability Compensation Act, "if the employee experiences wage loss from employment other than that in which the injury occurs, and that employment contributed *162 more than one-fifth of the employee's average weekly wage." Op. at 160. Section 372 is simply not triggered if there is nothing to apportion.
However, I dissent because I believe that it is not necessary to remand this case. The magistrate found that the plaintiff's injury rendered her compensably disabled from one employment but not compensably disabled from her concurrent employment. The magistrate correctly concluded that plaintiff was partially disabled because she retained a wage earning capacity in work suitable to her qualifications and training. Further, the WCAB agreed with these findings and conclusion.[1] I believe that the majority's decision to remand is functionally equivalent to a reversal of the finding of partial disability because it ignores both the magistrate's and the WCAB's findings that the plaintiff retained a wage earning capacity.
The magistrate already explored the "complex of fact issues" that informs the analysis of "wage earning capacity." The majority's attempt to cleave the concept of "wage earning capacity" from the concept of "disability", op. at 158-159, undermines the legislature's unmistakable intent to define compensability by a marriage of those very concepts: "`disability' means a limitation of an employee's wage earning capacity in work suitable to his or her qualifications and training resulting from a personal injury or work related disease." M.C.L. § 418.301(4); M.S.A. § 17.237(301)(4). See Michales v. Morton Salt Co., 450 Mich. 479, 490, 538 N.W.2d 11 (1995). While it is true and very regrettable that this plaintiff's activities are "severely limited," op. at 159, this fact does not force reconsideration of the magistrate's conclusion that this plaintiff retained a wage earning capacity at sedentary employment.
Furthermore, including wages from "all employment" in the definition of average weekly wage under § 371(1) did not change the basic definition of compensable disability. The addition of "all employment" in 1982 was intended to address the inequity of prior case law, as discussed by the majority opinion. Op. at 159. Prior case law did not consider wages earned at a second job even when the injury affected the employee's wage-earning capacity at the second job.[2] The addition of the "all employment" resolved that very specific problem.[3]
In this case, the magistrate found that the plaintiff is not compensably disabled from sedentary employment. In other words, she retains a wage earning capacity in work suitable to her qualifications and training: she is still fully able to earn wages at a similar sedentary job. It is also clear that the subsequent loss of the sedentary job was unrelated to plaintiff's compensable disability. It is fundamentally inconsistent with Michigan's wage-loss system to compensate an employee when the subsequent loss of a second job is in no way related to her compensable disability and when she retains a wage earning capacity for other work comparable to the second job.
Whether the eventual closing of the drive-in was inevitable is not relevant to the determination of the employee's earning capacity and, further, it is not the purpose of the Michigan's Worker's Disability Compensation Act to serve as another form of unemployment insurance.
I would reverse the judgment of the Court of Appeals and reinstate the decision of the magistrate as modified by the WCAB and to the extent that it is consistent with this opinion.

[8]  While the incapacity for work resulting from a personal injury is partial, the employer shall pay, or cause to be paid to the injured employee weekly compensation equal to 80% of the difference between the injured employee's after-tax average weekly wage before the personal injury and the after-tax average weekly wage which the injured employee is able to earn after the personal injury, but not more than the maximum weekly rate of compensation, as determined under section 355. Compensation shall be paid for the duration of the disability. [M.C.L. § 418.361(1); M.S.A. § 17.237(361)(1) (emphasis added).]
[9]  If an employee was engaged in more than 1 employment at the time of a personal injury or a personal injury resulting in death, the employer in whose employment the injury or injury resulting in death occurred is liable for all the injured employee's medical, rehabilitation, and burial benefits. Weekly benefits shall be apportioned as follows:

(a) If the employment which caused the personal injury or death provided more than 80% of the injured employee's average weekly wages at the time of the personal injury or death, the insurer or self-insurer is liable for all of the weekly benefits.
(b) If the employment which caused the personal injury or death provided 80% or less of the employee's average weekly wage at the time of the personal injury or death, the insurer or self-insurer is liable for that portion of the employee's weekly benefits as bears the same ratio to his or her total weekly benefits as the average weekly wage from the employment which caused the personal injury or death bears to his or her total weekly wages. The second injury fund is separately but dependently liable for the remainder of the weekly benefits. The insurer or self-insurer has the obligation to pay the employee or the employee's dependents at the full rate of compensation. The second injury fund shall reimburse the insurer or self-insurer quarterly for the second injury fund's portion of the benefits due the employee or the employee's dependents.

[11]  As used in this chapter, "disability" means a limitation of an employee's wage earning capacity in work suitable to his or her qualifications and training resulting from a personal injury or work related disease. The establishment of disability does not create a presumption of wage loss. [M.C.L. § 418.301(4); M.S.A. § 17.237(301)(4).]
[12]  As used in this act, "average weekly wage" means the weekly wage earned by the employee at the time of the employee's injury in all employment, inclusive of overtime, premium pay, and cost of living adjustment, and exclusive of any fringe or other benefits which continue during the disability. Any fringe or other benefit which does not continue during the disability shall be included for purposes of determining an employee's average weekly wage to the extent that the inclusion of the fringe or other benefit will not result in a weekly benefit amount which is greater than 2/3 of the state average weekly wage at the time of injury. The average weekly wage shall be determined by computing the total wages paid in the highest paid 39 weeks of the 52 weeks immediately preceding the date of injury, and dividing by 39.

[T]he employer in whose employment the injury occurred will be liable ... for all or part of the amount of the regular weekly disability... benefits payable to the employee ..., with the Second Injury Fund assuming liability for the remaining amount of the weekly benefits payable to the employee.... If the employment which caused the injury ... provided more than four-fifths of the employee's average weekly wages from all employments at the time of the injury, that employer ... will be liable for the full amount of the regular weekly benefits.
