摘要：Modern trademodels attribute the dispersion of international prices to physical andman-made barriers to trade, to the pricing-to-market by heterogeneous producers and to differences in the quality of output offered by firms. This paper presents a tractable general equilibrium model that incorporates all three of these mechanisms. Our model allows us to confront Chinese firm-level data on the prices charged and revenues earnedwithin and across markets. We show that all three mechanisms are nece...

摘要：A key parameter in international economics is the elasticity of substitution between domestic and foreign goods, also called the Armington elasticity. Yet estimates vary widely. We collect 3524 reported estimates of the elasticity, construct 32 variables that reflect the context in which researchers obtain their estimates, and examine what drives the heterogeneity in the results. To account for model uncertainty, we employ Bayesian and frequentist model averaging. To correct for publication bi...

摘要：This paper develops a simple and tractable model of net capital flows in which time-varying gross country portfolios are an essential element in current account imbalances. The main constituents of country portfolios in the model are general derivatives, which could be interpreted as nominal bond assets and liabilities in particular. Under very weak conditions, the world wealth distribution is stationary. Stationarity is generated by movements in derivative (i.e., bond) risk-premia such that t...

摘要：A central prediction of international trade models is that increased integration leads to specialization. This mechanism has been used to gain insight into the location of industries across countries, the reallocation of output across firms as well as the variation of a firm's product range as countries liberalize. Nevertheless, the notion that international trade will lead firms to rationalize their product portfolios and concentrate on their best products doesn't always square with reality. ...

摘要：We estimate Cobb-Douglas production functions that parameterize unobserved total factor productivity as a global technology process interacted with country-specific absorptive capacities. In contrast to the existing literature we do not require proxies for these absorptive capacities but instead estimate them as time-varying stochastic processes. Our implementation allows us to test the contrasting predictions of alternative growth models and our results for a panel of advanced economies suppo...

摘要：We propose a novel explanation for classic international macro puzzles regarding capital flows and portfolio investment, which builds on modern macro-finance models of experience-based belief formation. Individual experiences of past macroeconomic outcomes have been shown to exert a long-lasting influence on beliefs about future realizations, and to explain domestic stock-market investment. We argue that experience effects can explain the tendency of investors to hold an over proportional frac...

摘要：In this paper, we investigate the effects of trade in foods on obesity in Mexico. To do so, we match data on Mexican food imports from the U.S. with anthropometric and food expenditure data. Our findings suggest that exposure to food imports from the U.S. can explain up to 20% of the rise in obesity prevalence among Mexican women between 1988 and 2012. Pro-obesity effects are driven by areas more exposed to unhealthy food imports. We also find evidence in favour of a price mechanism. By linkin...

摘要：This study proposes a novel channel through which trade liberalization may induce innovation through the reduction of trade policy uncertainties (TPU) in destination markets. To verify this linkage, we utilize the significant reduction of TPU engendered by China's accession to the World Trade Organization (WTO) in 2001 as a quasi-natural experiment. We find that reduction in TPU significantly encourages firms' patent application: firms in sectors with a larger reduction in uncertainty filed mo...

摘要：In the context of the European crisis, we show that the security portfolio of banks plays an important role in the propagation of financial shocks across countries. Using Italian loan-level data, we show that the shock to the banks' sovereign portfolio caused by the 2010 Greek bailout was passed on to Italian firms through a credit contraction. This was particularly the case for banks with a lower capital and less stable funding. The contraction in credit was similar for both large and small f...

摘要：We explore the implications of judicial learning for trade disputes through a model where both the initiation of disputes and the occurrence of rulings are endogenous, governments bargain in the shadow of the law. and the efficiency of the court increases with experience. Judicial learning can explain litigation on the equilibrium path, since going to court today implies future payoff gains for the governments. Our model predicts that where learning is present the likelihood of both disputes a...
