On the size of government spending multipliers in Europe

This article compares the size of government spending multipliers in Europe by applying a panel structural vector autoregression analysis on 11 eurozone and 8 non-eurozone countries using quarterly data from 1991Q1 to 2012Q4. We find that (i) spending multipliers are smaller in eurozone compared to non-eurozone countries, (ii) across the euro area the impact of government spending on GDP has been higher before than after the introduction of the euro, (iii) spending multipliers are larger in the eurozone periphery than in the core countries and (iv) since the beginning of the recent financial crisis, spending multipliers have become larger both for eurozone and for non-eurozone countries. We relate these results to an emerging theoretical literature linking the size of fiscal multipliers to the monetary policy stance. We also discuss the implications of our findings for the effectiveness of fiscal policy in Europe.     

Estimation of treatment effects: recent developments and applications

The literature on the estimation of treatment effects has matured in economics. The potential outcomes framework guides the estimation of the causal effect of economic choices or policy interventions. The application of methods from the treatment effects literature has spread from the analysis of the effects of labor market programs and the wage return to education to other areas in economics. This special issue involves methodological developments and state-of-the art applications of methods to estimate treatment effects in various areas of economics. The contributions illustrate the emphasis within the treatment effects literature on the separate but related issues of heterogeneous treatment effects and identification. The careful, high-quality substantive applications collected here show just how much applied work on policy-relevant topics has benefitted from the methodological developments in the treatment effects literature. At the same time, many of the substantive papers make important methodological contributions as well.     

INTEREST RATES IN GROUP LENDING: A BEHAVIOURAL INVESTIGATION

Abstract.  Microfinance institutions (MFIs) serve more than 5 million households in developing countries. A crucial variable for MFI schemes is the interest rate to be charged from borrowers. This paper studies the behavioural impacts of the repayment burden on repayment performance. In a laboratory experiment, we vary the amount a borrower group has to repay and study how this affects free-riding behaviour. We can identify two counteracting effects: a higher repayment burden intensifies the incentives to free-ride as shirking saves more money. On the other hand, high-interest loans are less tolerant towards defaulters, which exerts a disciplining effect.

Spatial Competition with an Outside Good and Distributed Reservation Prices

In this paper, we analyze spatial competition within the framework of a Hotelling model with quadratic transportation costs and an outside option. The new feature of our approach is that consumers are uniformly distributed not only along the Hotelling line but also with regard to reservation prices. It turns out that in this particular model, duopolists always locate their shops exactly at the first and third quartile of the consumer distribution – i.e., at the socially optimal locations. Moreover, with uniformly distributed reservation prices, less than seventy percent of the consumers buy the good, and profits are less than fifteen percent of those in the standard model without an outside option.
