The Worker’s Job-Prospect Calculation
For a worker considering a young firm, the important object is not the first paycheck but the value of the employment path attached to it. This chapter follows that path through matching, employment, on-the-job search, retention, layoff, and firm exit. It explains how the worker’s outside option and the firm’s promises determine what the job is worth, and why the same uncertainty that produces a premium at one young firm can produce a discount at another.
A job is a path through changing states
The worker begins either unemployed or employed elsewhere. An unemployed worker has a value for remaining without a job, including unemployment insurance and the chance to search again in the next period. A job offer is attractive when its promised value exceeds that outside option by enough to justify the chance of matching. The worker is not choosing only between this wage and zero income; they are choosing between different paths through future employment states.
That expected value has several moving parts. The current wage matters immediately, but the worker also values the probability of receiving future wages, the chance of remaining with the firm, and the possibility of finding a better job later. A young firm with a high likelihood of hiring and retaining workers can offer a more valuable path than its current wage alone suggests. A firm likely to shrink or exit offers a path that ends sooner, even if it makes the first period look attractive. The model turns this ordinary intuition into a labor-market object that can be compared across firms.
The directed-search model represents those choices with labor-market submarkets. Each submarket is associated with a promised utility level and a matching probability. A worker can search for a more valuable contract, but a market with more demanding terms may have fewer vacancies or a lower chance of producing a match. A less demanding market may be easier to enter but offer a weaker job. The worker’s decision is therefore a trade-off between the value of the contract and the probability of obtaining it.
Firms face the matching trade-off from the other side. To recruit, a firm posts a vacancy and pays a cost, then chooses where to search for workers. A market promising more utility can attract workers, but it may require a more expensive contract or have a different chance of filling the vacancy. In the directed-search setup, firms compete for workers through the terms they promise rather than through a single anonymous pool. This matters for young firms because a weak or uncertain continuation path cannot be hidden by the current wage: workers can direct their search toward offers that compensate them more reliably.
That trade-off changes after employment. An employed worker at a young firm receives a current wage, but also retains a current employer as an outside option. They can search on the job for another firm, usually by targeting a contract that offers more value than the job they already hold. A successful search moves the worker to another employer without an intervening spell of nonemployment. If the search fails, the worker remains where they are. The value of staying is not simply the wage already paid; it includes what the current firm promises to provide in the future.
The possible transitions are consequential because each one preserves or destroys different parts of the worker’s position. Staying preserves the current firm relationship and its continuation promise. Moving preserves employment but replaces that relationship with a new one. A layoff or firm exit breaks the employment relationship and sends the worker to unemployment in the model. The worker then loses the current firm’s promised future value and must rely on the unemployment value and a new search opportunity. This is why firm survival and labor-market mobility belong in the same calculation.
The timing also matters. In the model, workers who are laid off in a period cannot immediately search as if they were still employed; they enter the unemployment pool and search in the following period. A worker who moves directly from one job to another avoids that interim nonemployment state. Thus, two separations with the same final employer can have different values: a job-to-job move preserves continuity, while an exit or layoff imposes a gap and a weaker immediate outside option. Young-firm uncertainty is costly partly because it raises the chance of the more disruptive transition.
The state diagram is not a claim that every worker follows a fixed sequence. The worker can move repeatedly between employment and search, while a layoff or exit creates a particularly costly break. In the model, the relevant worker differences are employment status and the current employer’s state; it does not add a separate process of human-capital accumulation or ex-ante worker types. That simplification keeps attention on how the employer’s prospects and the labor market alter the value of a match.
A young firm’s uncertainty enters at every transition. Before joining, the worker asks whether the firm will continue and whether the promised job value is credible. After joining, the worker’s decision to stay depends on whether the firm is likely to retain them and whether another firm can offer a better future. If the firm contracts, lays off workers, or exits, the expected path changes even if the current wage had been satisfactory. A wage is therefore the visible part of a contract whose economic content is the sequence of states the worker expects to face.
Outside options determine the price of uncertainty
The firm cannot simply announce an attractive number and assume that workers will stay. In the model, contracts include a current wage and state-contingent promises about what happens next: the possibility of firm exit or layoffs and the worker’s continuation utility, while workers remain free to search elsewhere. The firm must make its promise valuable enough to retain them. The promise is a control variable for the firm because it influences the worker’s on-the-job search target and, therefore, the risk that an incumbent will be poached.
The distinction between a new hire and an incumbent is important. A new hire compares the young firm’s offer with unemployment or a previous employer. An incumbent compares the promised future at the current firm with the value of searching elsewhere. The firm can write a contract that preserves a worker’s future value if the firm reaches the relevant state, but it cannot force the worker to ignore a better outside offer. The current wage is then backed out of the value the contract promises after accounting for expected separation, search, and continuation. It is compensation designed around a worker’s feasible alternatives, not a number set independently of them.
This creates a two-sided relationship between retention and labor cost. A firm that expects to expand has more reason to keep its existing workers. Losing them means paying vacancy costs and searching for replacements, so it can offer a stronger continuation value to discourage poaching. A contracting firm has less reason or ability to make the same promise. Workers recognize this difference: a firm likely to hire or retain them offers a more stable and valuable future than one likely to lose workers, lay them off, or close.
The ordering of expected future value is consequently intuitive once the transitions are visible. Workers expect more from firms that are hiring or retaining workers and less from firms experiencing quits, layoffs, or exit. The expectation is not only about present profitability. It includes the chance of remaining employed, the quality of the next contract, and the worker’s ability to move if the current relationship deteriorates. Two jobs with the same current wage can therefore have different values when their continuation states differ.
Search frictions determine how much those differences matter. If workers can move quickly between firms, a disappointing match is less damaging. The worker can leave before a bad prospect becomes a layoff, and a firm does not need to compensate as heavily for uncertainty that can be escaped. If matching is slow or vacancies are scarce, the same young-firm failure exposes the worker to a longer period without employment. The worker’s outside option is weaker, so the young firm must offer more value to make the match worthwhile.
There are two related mobility margins here. An unemployed worker needs a market in which to find a job at all. An employed worker needs the ability to search without giving up the current job first. The second margin changes the bargaining position inside a young firm: a worker who can test an outside offer while employed is less dependent on the firm’s promise, and the firm must retain them rather than relying on the cost of departure. Lower friction therefore changes both the probability of recovering from failure and the pressure on the firm to make its continuation value credible.
This is the labor-market meaning of an outside option. It is not merely a reservation wage written in isolation from the market. It is the expected value of the alternatives the worker can realistically reach, including the probability of finding them. A high nominal offer at a young firm may be less attractive than a lower offer at a mature firm if the latter provides a more reliable continuation path and the worker has little ability to move. The comparison changes again for a worker in a fluid labor market with many accessible alternatives.
The same logic explains why the model’s wage differences are performance-contingent. Consider a high-performing young firm and a mature firm with the same current and past-average performance, size, and worker status. The young firm’s workers still face more uncertainty about whether its performance reflects a durable type. Their expected future value is therefore lower than it would be at the mature counterpart unless the young firm raises the terms of employment. In equilibrium, the young high-performing firm pays a wage premium to make the uncertain path sufficiently attractive.
Now compare low-performing young and mature firms with similarly weak observed performance. The young firm remains concerning, but its short record leaves more room for the possibility that the poor results are temporary. That unresolved upside can make the expected value of the young firm higher than the value of an equally weak mature firm, whose long record has already revealed more about its limitations. The young low-performing firm can consequently pay a discount. The worker is not being told that the firm is safe; the worker is accepting a different distribution of possible futures.
This asymmetry would be hard to see in a model that treated firm age as a simple risk label. A single age penalty assumes that every young firm creates the same problem. Here, age changes the interpretation of the firm’s evidence, and the worker’s outside option changes the cost of being wrong. High performance is under-credited when the history is short; low performance is less conclusive for the same reason. Search frictions then scale both effects by determining how readily the worker can recover from a bad outcome.
Lower search frictions narrow the wage differences in both directions. A worker who can move more easily is less dependent on the current firm’s promised future value, so a high-performing young firm needs a smaller premium to recruit and retain them. At the other end, a weak young firm loses the benefit of an unresolved upside when workers can quickly test other opportunities; its discount becomes smaller, but its ability to keep workers also weakens. The change improves selection: stronger young firms can grow without as large a labor-market tax, while weaker firms are less protected from worker departure and may exit sooner.
This is a selection effect, not simply a transfer from firms to workers. Easier movement can help a strong young firm because it reduces the extra wage required to persuade workers to take a chance on an unproven employer. It can also expose a weak firm sooner, because workers do not have to remain while waiting for its potential to become clear. The labor market then becomes better at sorting workers toward firms whose prospects justify continued expansion. The result depends on the model’s assumptions, but it shows why employment mobility can affect the population of surviving young firms, not only the pay of people who move.
The model’s quantitative exercises treat this result as a mechanism to be evaluated under specified assumptions, not as a forecast for any particular job platform or search policy. The qualitative point is broader and easier to test: when workers have fewer alternatives, future prospects should matter more in the terms young firms must offer; when alternatives become easier to reach, age-related compensation gaps should shrink. Evidence that showed no relationship between mobility and the wage pattern would weaken this part of the explanation, even if the average young-firm wage result remained.
The worker’s calculation thus joins three elements that are often separated. The first is information: what does the firm’s record reveal about its underlying potential? The second is continuation: what happens if the firm grows, contracts, retains the worker, or exits? The third is mobility: how costly is it to search for another job? Current pay is the contract’s observable entry point, but expected future value is what makes the wage high or low relative to an apparently similar mature employer.
A young firm can therefore face a labor-market tax even when its measured productivity looks strong. It has to persuade workers that the uncertain future is worth entering, while also paying enough to prevent a successful match from being poached. Better evidence about its potential and a labor market with more accessible alternatives reduce that tax, but they do so through different channels. The first changes how workers interpret the firm; the second changes how exposed workers are to the interpretation being wrong.
