Abstract

This paper investigates how institutional rigidities shape inflation persistence in transition economies, focusing on labor market institutions and exchange rate regimes. Using a large panel of transition countries over the period 2013-2024, the analysis combines newly constructed indices of wage rigidity and labor protection, derived from AI-assisted coding of legal texts, with de facto measures of exchange rate regime rigidity and standard macroeconomic controls. The empirical strategy adopts a dynamic panel framework in which inflation persistence is conditioned on institutional characteristics through interaction terms, estimated using GMM techniques. Identification follows a cohort-based approach, comparing inflation dynamics across countries with different institutional configurations. To address potential measurement and classification uncertainty in institutional variables, the analysis incorporates a simulation-based sensitivity framework. The results show that inflation persistence varies systematically across institutional settings. Both wage rigidity and exchange rate regime rigidity tend to dampen inflation persistence, indicating that institutional constraints can weaken the transmission of past inflation into current price dynamics. This effect is particularly strong and robust for exchange rate regimes, while the effect of wage rigidity is more sensitive to measurement assumptions. Findings highlight the importance of institutional structures in shaping inflation processes and suggest that nominal rigidities may play a stabilizing role in certain macroeconomic environments.

Local Media and the Shaping of Social Norms: Evidence from the Ebola outbreak

Media's influence on norms and behavior is widely recognized. Less is known about the role played by media being local. I examine this in a high-stakes context, the Ebola outbreak in Guinea. I exploit quasi-random variation in access to radio and the timing of a public-health campaign aired on community radio. I find that 12-17% of Ebola cases could have been prevented if places with access to a neighboring community radio station had instead had their own. Impacts are driven by radio being local rather than by ethno-linguistic belonging. Local media facilitates coordination in behaviors observed and sanctioned locally.

Productivity Shocks and Input Misallocation: A Decomposition

This paper asks how much input misallocation productivity uncertainty generates and at which stage of input decisions it arises. I separate revenue productivity by when each component is revealed and trace each into the gap between an input's marginal revenue product and its price. In six European countries, shocks revealed after an input is committed account for 20 percent of capital gap dispersion and 5 percent of labor gap dispersion. An unanticipated one percent rise in productivity raises the capital gap by 0.92 percent and the labor gap by 0.19 percent, because most of the shock passes into the wage.

When Do Type-Specific Wages Buffer Distributional Incidence in TANK?

When do relative wages buffer the unequal incidence of aggregate shocks? I derive a consumption-gap decomposition and a present-value condition for partial offset in a TANK model. An extension separates wage-setting demand elasticity from substitution between labor segments and allows each segment to contain both financial types. With a zero inherited wage gap and a same-sign discounted wedge, substitution above one gives offsetting earnings reallocation; substitution below one gives amplification. The channel disappears when financial types have identical segment exposure. Numerical experiments assess these mechanisms, shock persistence, policy feedback, and aggregate-IRF matching. In the nested perfect-alignment monetary benchmark, the peak consumption gap is about two-fifths smaller under type-specific wages than under the common-wage closure. These are conditional model comparisons, not empirical effect estimates or welfare rankings.
