In recent decades, information and communication technology (ICT) has been associated with far-reaching changes in the design of jobs. However, it still remains unclear whether these changes will lead to more centralization or more decentralization in firms. Previous literature on this debate...

It is commonly argued that labor market institutions such as employment protection worsen an economy's performance and particularly so, if product markets become more competitive. Empirical evidence, however, has difficulties to detect a robust negative correlation between employment protection...

This paper develops a model in which market structure is determined endogenously by the choice of intermediation mode. We consider two representative business modes of intermediation that are widely used in real-life markets: one is a middleman mode where an intermediary holds inventories which...

In this paper I analyze adolescent peer effects on cigarette consumption while considering the 'popularity' of peers. The analysis is based on AddHealth data, a four wave panel survey representative of American high-school students. The data include the social network of each school, which we...

Although market concentration is one of the main impediments to productivity growth globally, data constraints have limited its analysis to developed countries or cross-country studies based on definitions of market concentration across nations and industries. This paper takes advantage of a...

We develop and estimate a model of child care markets that endogenizes both demand and supply. On the demand side, families with a child make consumption, labor supply, and child-care decisions within a static, unitary household model. On the supply side, child care providers make entry, price,...

In the last decade, social media and the Internet have amplified the possibility to spread false information, a.k.a. fake news, which has become a serious threat to the credibility of politicians, organizations, and other decision makers. This paper proposes a framework for investigating the...

This paper presents a tractable formalization and an empirical investigation of the quality-complementarity hypothesis, the hypothesis that input quality and plant productivity are complementary in generating output quality. We embed this complementarity in a general-equilibrium trade model with...

Do firms employing undocumented workers have a competitive advantage? Using administrative data from the state of Georgia, this paper investigates the incidence of undocumented worker employment across firms and how it affects firm survival. Firms are found to engage in herding behavior, being...

This paper assesses the impact of product market competition on job instability as proxied by the use of fixed-term labor contracts. Using both worker data from the Spanish Labor Force Survey and firm data from the Spanish Business Strategies Survey, I show that job instability rises with...
