摘要：Little is known about the economic mechanisms leading to the high level of clustering in behaviour commonly observed in the data. We present a model where agents can interact according to three distinct mechanisms and we derive testable implications which allow us to distinguish between the proposed mechanisms. In our application we study students' performance and we find that a mutual insurance mechanism is consistent with the data. Such a result bears important policy implications for all th...

摘要：We develop a model of cultural transmission where television plays a role in socialisation. We study the coverage of different cultural traits by a profit-maximising TV industry and the resulting cultural dynamics. A monopolist covers both traits, but grants more coverage to the most profitable group. In a competitive TV industry each channel specialises on one trait. This might lead to cultural extinction, but only for sufficiently large majorities. Cultural extinction is more likely in a com...

摘要：We examine individual-level compensating differentials for commuting distance in a quasi-natural experiment setting by examining how wages respond to changes in commuting distance induced by firm relocations. This set-up enables us to test for the relevance of job search frictions within labour market models. Due to the quasi-experimental set-up, we are able to avoid a range of endogeneity issues. We demonstrate that a 1 km increase in commuting distance induces an almost negligible wage incre...

摘要：We re-examine the literature on mobile termination in the presence of network externalities. Externalities arise when firms discriminate between on and off-net calls or when subscription demand is elastic. This literature predicts that profit decreases and consumer surplus increases when termination charges increase. This is puzzling as in reality regulators are pushing termination rates down while being opposed to do so by network operators. This puzzle is resolved when consumers' expectation...

摘要：Existing search and bargaining models show that firms hire an inefficiently large number of workers. We ask whether decentralised collective wage bargaining may result in a second-best allocation. Collective bargaining restores efficiency when the bargained wage is independent of employment; conditions that we characterise. Firms then behave as if collective bargaining was over both wages and employment, thus linking the large-firm search and bargaining environment to the efficient bargaining ...

摘要：In Sweden, children typically start school the year they turn seven. We combine this school entry cutoff with individuals' birthdates to estimate effects of school starting age (SSA) on educational attainment and long-run labour market outcomes. We find that school entry age raises educational attainment and show that postponing tracking until age 16 reduces the effect of SSA on educational attainment. On average, SSA only affects the allocation of labour supply over the life-cycle and leaves ...

摘要：We use experiments to study market power with supply function competition, akin to the competition in electricity markets. Our treatments vary the distribution of demand levels as well as the amount and symmetry of the allocation of production capacity between different suppliers. We relate our results to a descriptive power index and to the predictions of two models: a supply function equilibrium (SFE) model and a multi-unit auction (MUA) model. Observed behaviour is consistent with the equil...

摘要：In this study, we quantify the labour market effects of migration flows in OECD countries during the 1990s based on a new global database on the bilateral stock of migrants, by education level. We simulate various outcomes using an aggregate model of labour markets, parameterised by a range of estimates from the literature. We find that immigration had a positive effect on the wages of less educated natives and it increased or left unchanged the average native wages. Emigration, instead, had a...

摘要：Empirical analysis of social networks is often based on self-reported links from survey data. How we interpret such data is crucial for drawing correct inference on network effects. We propose a method for testing whether survey responses can safely be interpreted as a link and, if so, whether links are generated by a unilateral or bilateral link formation process. We present two empirical illustrations of the test on risk-sharing links in Tanzania and on communication among Indian farmers, re...
