摘要：This paper develops a two-country monetary DSGE model in which households choose a portfolio of home and foreign equities, and a forward position in foreign exchange. Some nominal goods prices are sticky. Trade in these assets achieves the same allocations as trade in a complete set of nominal state-contingent claims in our linearized model. When there is a high degree of price stickiness, we show that not much equity diversification is required to replicate the complete-markets equilibrium wh...

摘要：High interest rate currencies tend to appreciate relative to low interest rate currencies. We argue that adverse selection problems between participants in foreign exchange markets can account for this forward premium puzzle. The key feature of our model is that the adverse selection problem facing market makers is worse when an agent wants to trade against a public information signal. So, when based on public information, the currency is expected to appreciate, there is more adverse selection...

摘要：Accounting for observed fluctuations in aggregate employment, consumption, and real wage using the optimality conditions of a representative household requires preferences that are incompatible with economic priors. In order to reconcile theory with data, we construct a model with heterogeneous agents whose decisions are difficult to aggregate because of incomplete capital markets and the indivisible nature of labor supply. If we were to explain the model-generated aggregate time series using ...

摘要：This paper uses a dynamic stochastic general equilibrium (DSGE) model with sticky information as a laboratory to study monetary policy. It characterizes the model's predictions for macro dynamics and optimal policy at prior parameters, and then uses data on five US macroeconomic series to update the parameters and provide an estimated model that can be used for policy analysis. The model answers a few policy questions. How does sticky information affect optimal monetary policy? What is the opt...

摘要：We use oil price fluctuations to test the impact of transfers from wealthy OPEC nations to their poorer Muslim allies. The instrument identifies plausibly exogenous variation in foreign aid. We investigate how aid is spent by tracking its short-run effect on aggregate demand, national accounts, and balance of payments. Aid affects most components of GDP though it has no statistically identifiable impact on prices or economic growth. Much aid is consumed, primarily in the form of imported nonca...

摘要：Assassinations are a persistent feature of the political landscape. Using a new dataset of assassination attempts on all world leaders from 1875 to 2004, we exploit inherent randomness in the success or failure of assassination attempts to identify the effects of assassination. We find that, on average, successful assassinations of autocrats produce sustained moves toward democracy. We also find that assassinations affect the intensity of small-scale conflicts. The results document a contempor...
