Many developing countries use food-price subsidies or controls to improve nutrition. However, subsidizing goods on which households spend a high proportion of their budget can create large wealth effects. Consumers may then substitute towards foods with higher non-nutritional attributes (e.g., taste), but lower nutritional content per unit of currency, weakening or perhaps even reversing the subsidy's intended impact. We analyze data from a randomized program of large price subsidies for poor households in two provinces of China and find no evidence that the subsidies improved nutrition. In fact, it may have had a negative impact for some households.

We propose an origination-and-contingent-distribution model of banking, in which liquidity demand by short-term investors (banks) can be met with cash reserves (inside liquidity) or sales of assets (outside liquidity) to long-term investors (hedge funds and pension funds). Outside liquidity is a more efficient source, but asymmetric information about asset quality can introduce a friction in the form of excessively early asset trading in anticipation of a liquidity shock, excessively high cash reserves, and too little origination of assets by banks. The model captures key elements of the financial crisis and yields novel policy prescriptions.

We analyze whether the organizational structure of firms (i.e., whether a firm is diversified or focused) affects their cash holdings. Using Compustat firm level and segment-level data, we find that diversified firms hold significantly less cash than their focused counterparts. Our results are robust to industry adjustments at the segment level and to different factors previously found to be important determinants of cash holdings. Using time-series, cross-sectional, and additional robustness tests we are able to attribute the lower cash holdings among diversified firms to complementary growth opportunities across the different segments of these firms and the availability of active internal capital markets. We find that the other theories that rely on the potentially effective use of asset sales of non-core segments of diversified firms to generate cash, and the increased agency/influence costs in diversified firms do not offer an economically significant explanation for the lower cash holdings among diversified firms.
This paper investigates fire sales of downgraded corporate bonds induced by regulatory constraints imposed on insurance companies. As insurance companies hold over one-third of investment-grade corporate bonds, the collective need to divest downgraded issues may be limited by a scarcity of counterparties. Using insurance company transaction data, we find that insurance companies that are relatively more constrained by regulation are more likely to sell downgraded bonds. Bonds subject to a high probability of regulatory-induced selling exhibit price declines and subsequent reversals. These price effects appear larger during periods when the insurance industry is relatively distressed and other potential buyers' carpital is scarce.

We develop a model of financial contracting under imperfect enforcement. Financial contracts are designed to keep entrepreneurs from diverting project returns, but enforcement is probabilistic and penalties are limited. The model rationalizes the prevalence of straight debt and common stock, and its predictions are consistent with a host of empirical capital structure regularities.
Using data from the 2003 New Immigrant Survey, this paper examines whether stratification as reflected by skin shade exists among newly legalized Mexican immigrants in the US. While we do not find evidence that skin color directly related to employment probabilities, complexion appeared to play a role in the likelihood of owning a home, having a bank account, and occupational status. As these outcomes partly reflect immigrants' pre-migration experiences, our findings suggest that the social stratification structure in Mexico might be sustained in the US among Mexican-origin populations.
We find that repeated borrowing from the same lender translates into a 10–17 bps lowering of loan spreads and that relationships are especially valuable when borrower transparency is low. These results hold using multiple approaches (propensity score matching, instrumental variables, and treatment effects model) that control for the endogeneity of relationships. We also provide a demarcation line between relationship and transactional lending. Spreads charged for relationship loans and nonrelationship loans are statistically identical if the borrower is in the largest 30% by asset size; has public rated debt; or is part of the S&P 500 index. Past relationships reduce collateral requirements and are also associated with obtaining larger loans. Our results imply that, even for firms that have multiple sources of outside financing, borrowing from a prior lender obtains better loan terms.

We offer an explanation for the forward premium puzzle in foreign exchange markets based upon investor overconfidence. In the model, overconfident individuals overreact to their information about future inflation, which causes greater overshooting in the forward rate than in the spot rate. Thus, when agents observe a signal of higher future inflation, the consequent rise in the forward premium predicts a subsequent downward correction of the spot rate. The model can explain the magnitude of the forward premium bias and several other stylized facts related to the joint behaviour of forward and spot exchange rates. Our approach is also consistent with the availability of profitable carry trade strategies.

We document a statistical association between the severity of the persecution, displacement and mass murder of Jews by the Nazis during World War II and long-run economic and political outcomes within Russia. Cities that experienced the Holocaust most intensely have grown less, and both cities and administrative districts (oblasts) where the Holocaust had the largest impact have worse economic and political outcomes since the collapse of the Soviet Union. We provide evidence that the lasting impact of the Holocaust may be attributable to a permanent change it induced in the social structure across different regions of Russia.
