Definitions and precise research target

Complete editorial problem. Consider workers hired into specified occupations at baseline and a feasible work-location policy $r\in\{0,h,1\}$, denoting onsite, a declared hybrid schedule, and fully remote work. Let $Y_{it}(r)$ be earnings, $S_{it}(r)$ independently assessed skills, and $P_{it}(r)$ promotion status at date $t$. Let $X_i$ include baseline experience, occupation, and commuting constraints. Define $\tau_Y(r,x)=E[\sum_{t=0}^{T}\delta^t\{Y_{it}(r)-Y_{it}(0)\}\mid X_i=x]$, where $\delta\in(0,1]$ is a specified discount factor and $T$ the follow-up horizon. Estimate analogous skill and promotion effects and determine whether mentoring, contact with experienced coworkers, or evaluation practices mediate them. Initial onboarding and subsequent work location should be varied separately. Randomized location policies or credible quasi-experiments must address worker selection, endogenous exits, and effects on coworkers. Promotion differences alone cannot distinguish learning from managerial visibility. Evaluate benefits and losses for entrants separately from experienced workers. The cited call-center findings resolve some local productivity comparisons; extrapolating those results to long-term career development and other occupations is the proposed remaining empirical task.

Definitions and admissible scope. Write hybrid schedules as an explicit vector of onsite weekdays rather than a fraction with many possible meanings. Let $r$ denote assignment, not workers' chosen attendance, and $o$ an independent onboarding assignment. Baseline workers remain in the analysis after exit: earnings include all subsequent employers, promotion is separately coded as promotion at the initial firm or any firm, and skills are assessed independently of manager visibility. Define coworker exposure $s_i$ as a prespecified function of coworkers' assignments when interference matters. Effects then compare $Y_{it}(r,o,s_i)$ under stated joint assignment laws. Finite-horizon discounted earnings and skill outcomes have finite means. A mediation contrast requires a separately defined mentor intervention or defended sequential assumptions; the total work-location effect alone does not identify learning. Take $T<\infty$ to be a fixed integer, and fix the baseline cohort and weighting law. In the displayed one-argument $Y(r)$, onboarding is held at a declared $o_0$ and coworkers are assigned according to a declared joint location regime; when these vary, use $Y(r,o,s)$ explicitly. Skills and promotion are separate observed outcomes with fixed scales and finite expectations. For mediation, define a mentor intervention $m$ and controlled contrasts $E[Y(r,m)-Y(r,m')]$, or state the extra assumptions required for a natural-effect contrast. Work-location randomization alone identifies no such mediation effect. Report outcomes after exit under the fixed cohort convention.

Variants and assumption changes

  1. Onboarding by later location (source-motivated): randomize initial onsite contact and later work location independently. Estimate their interaction and retention effects for entrants; the call-center paper already reports local starter comparisons.
  2. Visibility versus learning (editorial): cross location assignment with blinded performance evaluation or standardized mentoring. Compare independently assessed skill gains with promotion effects over several years and define the population after worker exits.

Common conventions: Source mathematical conventions

These conventions apply to each entry unless explicitly replaced.

Models and identification. A primitive model $m$ specifies all probability laws, feasible choices, information, equilibrium and measurement rules used by its target. The admissible class $\mathcal M$ is fixed independently of outcomes. If $P_O(m)$ is its observable probability law and $\tau(m)$ the target, its identified set at observable law $P$ is \[ \mathcal I_\tau(P)=\{\tau(m):m\in\mathcal M,\ P_O(m)=P\}. \] Point identification means that this set is a singleton. An empty set signals incompatibility of data and assumptions. Coordinate bounds need not describe the joint set. Bounds are sharp only if every retained target is attainable or arbitrarily approachable by compatible models. Finite bounds require explicit restrictions on unobserved quantities; unrestricted confounding, hidden wealth, extrapolation or arbitrary equilibrium selection can yield uninformative sets.

Causal interventions. A potential outcome $Y_i(p)$ is the outcome under a complete policy regime $p$, including timing, financing, information and market spillovers. The target population and units are fixed before treatment. With interference, use the complete assignment vector or a justified exposure mapping; individual no-interference notation alone cannot identify an economy-wide intervention. A difference of mean potential outcomes does not require the cross-world joint distribution. Conditioning on post-treatment migration, survival, enrollment or employment changes the estimand and needs separate justification.

Statistical statements. An estimator, confidence set, forecast or test specifies a sampling law, model class and loss/coverage criterion. Uniform $(1-\alpha)$-coverage means $\inf_{m\in\mathcal M}\Pr_m\{\tau(m)\in C_n\}\geq1-\alpha$, or an explicitly asymptotic version. The whole parameter space trivially has coverage, so informativeness requires a stated width, risk or power objective. A forecasting improvement is relative to a named benchmark, information set and evaluation population.

Equilibrium and optimization. An equilibrium comprises feasible plans, optimality, beliefs where needed, budget constraints and all market/resource clearing. The primitives or a stated benchmark define each correspondence $\mathcal E(p;m)$. Nonemptiness is assumed or proved, never inferred just from compact policy sets. A selected-equilibrium target uses a declared selection rule; a robust target quantifies over all permitted equilibria. Use suprema or infima unless attainment is established. An $\varepsilon$-optimal policy is feasible and within $\varepsilon$ of the finite optimum value. Report an empty feasible set separately.

Welfare and accounting. Normative utility, interpersonal normalization, social weights, numeraire, discounting and the use of public receipts are primitives. Behavioral utility need not coincide with the welfare criterion. Household welfare includes ownership income and rents once; adding profits again to compensating variation generally double-counts them. A monetary equivalent is defined by an explicit transfer and price convention, with monotonicity and range conditions. Average effects, mechanism contributions, transfers and welfare losses are different targets. Infinite sums require convergence and dynamic feasible plans require terminal or no-Ponzi conditions.

Source versions. A working-paper date, revision date and journal publication year are distinguished. A DOI for a journal version is not automatically the DOI of an earlier manuscript. Locators refer to the stated version and printed pages where specified. A metadata-only check does not verify a claim about a full-text conclusion. Every entry's source subsection narrows the provenance claim accordingly.

Remote work and career development: separating learning, visibility and worker retention

Target and scope

For a fixed entrant cohort, location is a versioned assignment $r$, onboarding is $o$, and coworker exposure follows a specified joint regime. The principal earnings contrast is \[ \tau_Y(r)=E\sum_{t=0}^T\delta^t\{Y_t(r,o_0)-Y_t(0,o_0)\}. \] Skill and promotion effects are separate targets. The call-center study [remote] examines employee composition, performance and initial in-person contact; it does not by itself establish a general long-term career effect. The following design identifies a policy contrast for removing evaluation visibility and shows why observed promotions or retained employees alone cannot identify learning.

A factorial visibility experiment

For simplicity compare onsite $R=0$ with a specified remote schedule $R=1$. Hold onboarding fixed or randomize it as a separate factor. Let $B=1$ mean a blinded evaluation protocol and $B=0$ the ordinary evaluation protocol. Assign $(R,B)$ independently of the entire potential-outcome array, with positive probability for all four cells, consistency, and no interference across assignment clusters. Keep the baseline cohort after employer exit; promotion at the original firm and promotion anywhere are different outcomes and must be separately coded.

Let $S(r)$ be an independently assessed skill measure. Assume evaluation blinding does not change acquired skill, and impose the following explicit mean model: \[ E[P(r,b)\mid S(r),X]=h(S(r),X)+(1-b)v_r(S(r),X), \] with all right sides in $[0,1]$. The common $h$ is the blinded promotion rule; the $v_r$ terms are evaluation-protocol increments. This rules out an additional location channel under blinded evaluation, an assumption not implied by randomization.

Theorem (An identified visibility-removal contrast): Let $p_{rb}=E[P\mid R=r,B=b]$. Under the stated experiment and mean model, \[ p_{11}-p_{01}=E[h(S(1),X)-h(S(0),X)], \] while \[ (p_{10}-p_{00})-(p_{11}-p_{01}) =E[v_1(S(1),X)-v_0(S(0),X)]. \] Both quantities are identified without observing the cross-world joint law of $S(1),S(0)$.
Proof: Randomization identifies each cell's potential promotion mean. Apply iterated expectation to the conditional mean model. At $b=1$ the $v$ term vanishes, giving the first difference. At $b=0$ it is added, and subtraction of the blinded difference gives the second identity. Each target is a difference of single-world expectations, so no cross-world coupling is needed. Independent skill assessment separately identifies $E[S(1)-S(0)]$, but nonlinear $h$ means that this average skill change need not determine the blinded promotion difference. ∎
The second quantity is the change in the location effect when the evaluation protocol is changed. Calling it a natural indirect effect, or a universal percentage of the career penalty due to visibility, would add assumptions absent from the theorem. If blinding changes mentoring, effort or promotion capacity, the stated mean model may fail even though the factorial experiment still identifies its four policy means.
Proposition (Promotions alone cannot choose between learning and visibility): A randomized location experiment observing only promotions can have the same law under a pure skill mechanism and a pure evaluation mechanism.
Proof: Choose two probabilities $0<p_0,p_1<1$. In model A, let $S(r)$ be Bernoulli with mean $p_r$, and set $P(r,0)=S(r)$; all evaluation is skill based. In model B, let $S(r)=0$ for both locations and set $P(r,0)=1\{U\le p_r\}$ with a uniform evaluation disturbance $U$. Assign location independently of the potential array. Both observed experiments have $P\mid R=r\sim\operatorname{Bernoulli}(p_r)$, while their skill effects are $p_1-p_0$ and zero. Couplings across locations are arbitrary and irrelevant to the observed-law equality. Independent skill measurement distinguishes this construction; promotion records alone do not. ∎

Retention is an outcome, not an inclusion rule

Let a bounded career outcome $Y(r)\in[0,1]$ be observed only when $L(r)=1$, where $L$ may indicate remaining at the firm or successful follow-up. Randomized location identifies $p_r=P(L(r)=1)$ and $m_r=E[Y(r)\mid L(r)=1]$ when $p_r>0$.
Proposition (Sharp fixed-cohort attrition bounds): Without restrictions on missing outcomes, the full-cohort effect belongs to the sharp interval \[ [p_1m_1-p_0m_0-(1-p_0),\ p_1m_1+(1-p_1)-p_0m_0]. \] The survivor contrast $m_1-m_0$ may have the opposite sign from the full-cohort effect.
Proof: Write $EY(r)=p_rm_r+(1-p_r)u_r$, with $u_r\in[0,1]$ the unobserved mean. Extremizing independently over $u_0,u_1$ gives the endpoints. Bernoulli or deterministic missing outcomes with those means, coupled arbitrarily across assignments, realize them without altering the observed law. For a reversal, take $p_1=1/2,m_1=1,u_1=0$ and $p_0=1,m_0=3/4$. The observed survivor contrast is $1/4$, but the full-cohort effect is $1/2-3/4=-1/4$. ∎
This example is about missingness. If earnings after exit are collected from an administrative source, exits need not make earnings missing, although initial-firm promotion still needs a declared coding rule.
Proposition (Randomized follow-up of leavers): After observing $L$, collect missing outcomes with indicator $V$ whose known probability is $\pi_r(X)>0$ among $L=0$, independent of $Y$ conditional on $(R,X,L=0)$. Then \[ EY(r)=E\left[L Y+(1-L)\frac{VY}{\pi_r(X)}\ \middle|\ R=r\right]. \] For independent randomized clusters with bounded inverse probabilities, bounded cluster averages of this score yield honest finite-sample intervals by Hoeffding's inequality.
Proof: For leavers, conditional independent collection makes $E[VY/\pi_r\mid R,X,L=0]=E[Y\mid R,X,L=0]$. For retained workers the observed score is already $Y$. Integrate over $X,L$ and use treatment randomization and consistency to recover the full-cohort potential mean. With assignment probabilities also bounded below, inverse-assignment-weighted cluster scores have known finite ranges and are independent across clusters, giving the concentration assertion. No independence among coworkers within a cluster is asserted. ∎
A separately randomized mentor intervention $M$ can identify controlled mentoring contrasts at each location. It does not identify the effect of naturally occurring mentor contact merely by conditioning on observed contact, because contact can respond to skill, manager preferences and exit risk.

Remaining gap

The results specify experiments and assumptions that distinguish three sources of apparent career differences. They do not establish the blinded-rule exclusion, measure long-run skills, or solve spillovers when remote coworkers change onsite workers' mentoring opportunities. Hybrid weekday schedules, onboarding and outside-employer careers must remain explicit treatment and outcome versions. The full cross-occupation long-run career question remains unresolved.

Completion Estimate

55%

This is a post hoc, heuristic estimate for the full catalogue target. The attempt identifies factorial visibility-removal contrasts, proves promotions cannot distinguish learning from evaluation, and gives sharp attrition bounds and randomized leaver-follow-up identification. Long-run earnings, skills and promotion effects still need observed follow-up, justified blinding exclusions, coworker spillover models, and evidence across occupations, onboarding versions and hybrid schedules.
