Endogenous business cycles and systematic stabilization policy*

We study the effects of fiscal policy rules on the determinacy of rational expectations equilibrium in a perfectly competitive monetary model with constant returns. Government spending implies a distortion of the monetary steady state due to the implied taxation. We show that policy rules that let the GNP share of government spending depend sufficiently negatively on increases in GNP stabilize the economy with respect to endogenous fluctuations for arbitrarily little distortion of the steady state at which stabilization occurs. The rules do not involve lump‐sum taxation, negative income taxation, or exact knowledge of the economy's laissez‐faire steady state.     

The failure of the monetary model of exchange rate determination

In this article, we test three popular versions of the monetary model (flexible price, forward-looking and real interest differential models) for the OECD member countries by applying Johansen cointegration technique. Based on country-by-country analysis, we conclude that monetary models do not provide the expected results. We reveal several shortcomings of the models and examine the building blocks of the fundamental version. Although researchers always blame the deviations from purchasing power parity as the reason for the failure of the monetary model, our analysis indicates that invalidity of Keynesian money demand function is also responsible for unfavourable results.     

Smarter through social protection? Evaluating the impact of Ethiopia’s safety-net on child cognitive abilities

Ethiopia’s productive safety net is the second largest Social Protection Program in sub-Saharan Africa and has been rolled out to almost 10 million beneficiaries since 2005; its effects are therefore of general interest. We provide the first estimates of its impact on children’s cognitive abilities. To identify impacts of this program, we exploit four rounds of data on a cohort of children surveyed repeatedly between 2002 and 2013. We find a small but significant positive effect of the programme on both numeracy skills and vocabulary. This is driven mainly by children in households that had graduated (left) the programme just before 2013. We argue that this is at least partially related to time allocation: graduates of the programme spent more time in school than continuing beneficiaries. We also find evidence that the maths (though not language) improvement is more pronounced for boys.     

EMU and European government bond market integration

In this study we adopt the CAPM-based model of Bekaert and Harvey (1995) to compare the differences in the relative importance of two sources of systemic risk (world and Eurozone) on Government bond returns, in two groups of countries in EU-15. Results show that euro markets are less vulnerable to the influence of world risk factors, and more vulnerable to EMU risk factors. However, they are only partially integrated. For their part, the markets of the countries that decided to stay out of the Monetary Union present a higher vulnerability to external risk factors.     

Remittances,financial development,and growth

Despite the increasing importance of remittances in total international capital flows, the relationship between remittances and growth has not been adequately studied. This paper studies one of the links between remittances and growth, in particular how local financial sector development influences a country's capacity to take advantage of remittances. Using a newly-constructed dataset for remittances covering about 100 developing countries, we find that remittances boost growth in countries with less developed financial systems by providing an alternative way to finance investment and helping overcome liquidity constraints. This finding controls for the endogeneity of remittances and financial development, does not depend on the particular measure of financial sector development used, and is robust to a number of robustness tests, including threshold estimation. We also provide evidence that there could be an investment channel trough which remittances can promote growth especially when the financial sector does not meet the credit needs of the population.
