We analyze the relationship between Microfinance Institutions (MFIs) and external donors, with the aim of contributing to the debate on “mission drift” in microfinance. We assume that both the donor and the MFI are pro-poor, possibly at different extents. Borrowers can be (very) poor or...

This paper shows that the fiscal multiplier for purchases of durable and investment goods is very small - much smaller than the multiplier for nondurable goods. Standard models predict small durables multipliers because private sector purchases of durable goods are highly intertemporally...

In a VAR model of the US, the response of the relative price of durables to a monetary contraction is either flat or mildly positive. It significantly falls only if narrowly defined as the ratio between new house and nondurables prices. These findings survive three identification strategies and...

Atkinson and Stiglitz show that with weakly separability, differential commodity taxes are unnecessary given an optimal nonlinear income tax. Deaton showed that with an optimal linear progressive income tax, commodity taxes are superfluous under weakly separable and linear Engel curves. Using...

This paper proposes a theory of commodity taxation in the presence of durable goods. Optimal commodity taxes depend on preference nonseparabilities between durable and nondurable consumption. In particular, the seminal Atkinson-Stigliz result fails and differential commodity taxes are optimal...

Why do people have kids in developed societies? We propose an empirical test of two alternative theories - children as 'consumption' vs. 'investment' good. We use as a natural experiment the Italian pension reforms of the 90s that introduced a clear discontinuity in the treatment across workers....

Credit rationing in the presence of asset inequality affects production and trade pattern in this paper, but not in the conventional way. A Ricardian general equilibrium framework with heterogeneous levels of asset ownership is developed to show that more equal asset distribution may contract...

We study the implications of credit constraints for the sustainability of product market collusion in a bank-financed oligopoly in which firms face an imperfect credit market. We consider two situations, without and with credit rationing, i.e., with a binding credit limit. When there is credit...

In U.S. data 1981–2012, unsecured firm credit moves procyclically and tends to lead GDP, while secured firm credit is acyclical; similarly, shocks to unsecured firm credit explain a far larger fraction of output fluctuations than shocks to secured credit. In this paper we develop a tractable...

This paper examines the role of tax evasion in explaining the business cycle in a DSGE model with a financial accelerator. For this purpose, we assume that financially constrained agents are tax evaders, taking advantage of an additional margin of flexibility in coping with adverse shocks. In...
