Abstract

In this paper, we study the patterns of ethnic endogamy in Croatia in relation to six ethnic groups between 1970 and 2015. We find that, over the 45-year period analyzed, the segmentation of the Croatian marriage market was weaker between Czechs and non-Czechs, Hungarians and non-Hungarians, Italians and non-Italians, and Slovaks and non-Slovaks than between Serbs and non-Serbs or Croats and non-Croats. This finding is substantiated by survey evidence revealing similar patterns on relative social distances between different ethnic groups in Croatia and Serbia. From a methodological perspective, we show that a plausible ranking of the degree of segmentation of the Croatian marriage market along ethnic lines can be obtained only when marital sorting is characterized by a carefully selected indicator. While a recently reinvented indicator captures sensible patterns of ethnic endogamy, the commonly applied odds-ratio fails to produce results consistent with survey evidence.

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.
