We show that in a canonical model with heterogeneous entrepreneurs, financial frictions, and an imperfectly elastic supply of capital, a fall in the interest rate has an ambiguous effect on aggregate economic activity. In partial equilibrium, a lower interest rate raises aggregate investment...

We study the interaction of customer capital and productivity through brand reallocation across firms. We develop a firm dynamics model with brands as transferable customer capital, heterogeneous firm productivity, and variable markups. We study the matching process between transferable brand...

We study the productivity effect of the German national minimum wage combining administrative firm datasets. We analyze firm- and market-level effects, considering output price changes, factor substitution, firm entry and exit, labor reallocation, and short- versus long-run effects. We document...

How does Artificial Intelligence (AI) affect the task content of work, and how do workers adjust to the diffusion of AI in the economy? To answer these important questions, we combine novel patent-based measures of AI and robot exposure with individual survey data on tasks performed on the job...

Wars disrupt labor markets, yet systematic evidence on how markets for labor services operate during conflicts is almost entirely absent. Ukraine is a rare exception: despite the full-scale Russian invasion, timely data on workers and vacancies, in both stocks and flows, remain available. We use...

We study conflicts between envy-based fairness and efficiency for allocating indivisible items under additive utilities. We formalize several small, transparent instances showing that standard envy-freeness (EF) or its relaxations EFX and EFX0-i.e., envy-freeness up to any item, where EFX...

This chapter takes stock of what has been learned from the recent micro-development literature about wedges - mechanisms generating dispersion in marginal revenue products of factors across firms, which are commonly interpreted as indicators of misallocation. We present a general theoretical...

Carbon leakage is a major concern in the design of unilateral climate policies aimed at reducing global emissions in a cost-effective manner. In order to assess the cost-effectiveness of anti-leakage measures, it is crucial to understand the fundamental mechanisms that contribute to leakage. We...

We study how variation in the allocation mechanism of public demand shapes firm performance and aggregate productivity. Exploiting the quasi-random implementation of an efficient or lottery-like auction format in the Italian construction sector, we find that when the same amount of public...

Bilateral trade shocks affect firms in third countries by redirecting demand and reallocating competition across markets, creating winners and losers. We propose a tractable trade model with heterogeneous firms to decompose firm-level export responses as a function of destination-specific...

This paper calculates the contribution of the reallocation of capital and labor to aggregate TFP for the 2000-2024 period in the Turkish economy. While the reallocation effect is generally positive for labor (except for crisis years), there are two separate periods for capital. In the period...

In this paper, we introduce a new class of cost allocation rules for rooted tree cost allocation problems that is based on the position value (Meessen 1988 and Borm et al. 1992). We further extend this by introducing a class of cost allocation rules that, besides these new position rules, also...

We develop a general sorting model that incorporates both self-selection by applicants, who assess their own skills, and evaluation by admissions agents, who rely on noisy signals of skills. Building upon the theoretical framework of the Roy model, our analysis examines how the presence of noise...

Artificial intelligence (AI) has become an integral driver of digital transformation in the banking sector, fundamentally influencing operational efficiency, resource allocation, and profitability. This study investigates how AI adoption affects the profitability of Chinese commercial banks and...

Distressed and zombie firms are widespread in economies with weak insolvency regimes. This study investigates whether reforming insolvency laws can reduce capital misallocation. We introduce a framework for decomposing financial misallocation and derive metrics adequate to capture two...

This paper examines how global greenfield foreign direct investment (FDI) flows are evolving amid rising geoeconomic fragmentation. We use difference-in-differences and event study approaches to analyze changes in FDI around key bilateral inflection points. We find a decline in FDI from the US...

This paper studies the employment and reallocation effects of minimum wages in Germany in a search-and-matching model with endogenous job search effort and vacancy posting, multiple employment levels, a progressive tax-transfer system, and worker and firm heterogeneity. I find that minimum wages...

This paper examines the resource mismatch in China's healthcare sector from 2010 to 2019. We use structural efficiency to measure the resource mismatch in the healthcare industry (0.2-0.7). We find that an increase in the proportion of private hospitals decreases the healthcare resource mismatch...

Children tend to choose the same occupations as their parents. We examine the implications of this tendency for talent allocation and intergenerational mobility. Using Swedish data on skills and personality traits, we estimate a general equilibrium Roy model with unequal occupational access...

We argue that capital misallocation arises endogenously due to incomplete consumption insurance. We model risk-averse entrepreneurs with heterogeneous productivity who face idiosyncratic output shocks and choose how much capital to rent before uncertainty unfolds. We show that incomplete markets...

This paper characterizes the short- and long-run Cournot equilibrium with heterogeneous firms and stochastic technological change. In our model, firms have different technologies with heterogeneous fixed and variable costs and various degrees of markups. In a framework with homogeneous firms,...
