This paper examines how wealth accumulation and risk sharing affect the evolution of inequality over time. We first assume risk sharing away and examine how inequality evolves over time when agents accumulate an asset. If asset accumulation is unbounded and the asset yields a positive return,...

Information asymmetries constitute a significant obstacle to capital flows across international borders, and in particular to flows of foreign investment (FDI) to emerging markets.  Many governments aim to reduce information barriers by emerging in investment promotion activities.  Despite...

A convergence model with wealth accumulation subject to i.i.d. random shocks is examined. The transfer function shows what k_{t+1} - wealth at t+1 - would be, given k_t, with no shock: It has a positive slope, but its concavity/convexity is indeterminate. The stationary distribution of wealth...

A convergence model in which wealth accumulation is subject to i.i.d. random shocks is examined. The accumulation functions shows what k_{t+1} - wealth at t+1 - would be given k_t and with no shock. It has a positive slope, but its concavity or convexity is indeterminate. The focus is the...

A large literature describes how local risk sharing networks can help individuals smooth consumption in the face of idiosyncratic economic shocks.  However, when an entire community faces a large covariate shock, and when the transaction costs of transfers are high, these risk sharing networks...

Combining data from the Moroccan census of manufacturing enterprises with information from a commune survey, we test whether firm expansion is affected by local financial development.  Our findings are consistent with this hypothesis: local bank availability is robustly associated with faster...

We present cross-country empirical evidence on the role of natural resources in explaining long-run differences in private investment as a share of GDP in a sample of 72 developing countries.  Our empirical results suggest important differences between oil and non-oil resources.  While revenue...

Standard models of investment predict that credit-constrained firms should grow rapidly when given additional capital, and that how this capital is provided should not affect decisions to invest in the business or consume the capital.  We randomly gave cash and in-kind grants to male- and...

Rational demand for hedging products, where there is a risk of contractual nonperformance, is fundamentally different to that for indemnity insurance.  In particular, optimal demand is zero for infinitely risk averse individuals, and is nonmonotonic in risk aversion, wealth and price.  For...

This paper analyses collusion-proof multilateral insurance contracts between a risk neutral insurer and multiple risk averse agents in an environment of asymmetric costly state verification.  Optimal contracts involve the group of agents pooling uncertainty and the insurer acting as reinsurer...
