Financial Intermediation Chains in an OTC Market
This paper analyzes financial intermediation chains in a search model with an endogenous intermediary sector. We show that the chain length and price dispersion among interdealer trades are decreasing in search cost, search speed, and market size but increasing in investors' trading needs. Using data from the U.S. corporate bond market, we find evidence broadly consistent with these predictions. Moreover, as search speed approaches infinity, the search equilibrium does not always converge to the centralized-market equilibrium: prices and allocation converge, but the trading volume might not. ...

Stability and Equilibrium Selection in Learning Models: A Note of Caution
Relative to rational expectations models, learning models provide a theory of expectation formation where agents use observed data and a learning rule. Given the possibility of multiple equilibria under rational expectations, the learning literature often uses stability as a criterion to select an equilibrium. This article uses a monetary economy to illustrate that equilibrium selection based on stability is sensitive to specifications of the learning rule. The stability criterion selects qualitatively different equilibria even when the differences in learning specifications are small.

Labor Market Stability and Fertility Decisions
This paper studies how fertility decisions respond to an improvement in job stability using variation from the large and unexpected regularization of undocumented immigrants in Spain implemented during the first half of 2005. This policy change improved substantially the labor market opportunities of affected men and women, many of which left the informality of house keeping service sectors toward more formal, stable, and higher paying jobs in larger firms (Elias et al., 2023). In this paper, we estimate the effects of the regularization on fertility rates using two alternative ...
