This paper provides evidence that transnational networks, defined as networks operating across nationalities, are shaping observed patterns of international migration. In a stylized model of migration with random friendship formation, individuals from a given origin country are attracted to...

This paper analyzes the role of ethnic communities in shaping the recent immigration boom to Spain. We find that ethnic communities exerted a strong positive effect on the scale and a strong negative effect on the skill structure of this immigration. Unlike previous studies, we explicitly...

Which firms find it optimal to integrate their input suppliers into the firm boundaries of control (vertical integration)? Which firms choose to expand their sourcing activities across the national border (offshoring)? This letter provides novel evidence on these questions based on a Spanish...

This paper studies to what extent individuals form their preferences towards trade policies along the lines of the Stolper-Samuelson logic. We employ a novel international survey data set with an extensive coverage of high-, middle-, and low-income countries, address a subtle methodological...

Technology leaders protecting a technological headstart with a patent are provided with a powerful legal measure to restrict market entry. We analyze the impact of knowledge spillover on the decision to patent and the effect of varying patent breadth on the threat of market entry. An empirical...

We present a theory that systematically and causally links the well-being of native inhabitants with variation in the extent of the assimilation of migrants. Recent empirical findings are yielded as predictions of the theory.

In three-person envy games, an allocator, a responder, and a dummy player interact. Since agreement payoffs of responder and dummy are exogenously given, there is no tradeoff between allocator payoff and the payoffs of responder and dummy. Rather, the allocator chooses the size of the pie and...

We study price competition in heterogeneous markets where price decisions are delegated to agents. Principals implement a revenue sharing scheme to which agents react by commonly charging a sales price. The results of our model exemplify the importance of both intrafirm- and interfirm...

What determines the risk structure of financial portfolios of German households? In this paper we estimate the determinants of the share of financial wealth invested in three broad risk classes. We employ a new econometric approach - the so called fractional multinomial logit model - which...

We present a model of price leadership on homogeneous product markets where the price leader is selected endogenously. The price leader sets and guarantees a sales price to which followers adjust according to their individual supply functions. The price leader clears the market by serving the...
