Good governance and good aid allocation

We model the aid allocation process as a rent-seeking contest between two countries and investigate the effects of differing allocation rules on recipients' behavior in a simple framework. We investigate the aid allocation mechanism design that attempts to increase the governance quality of potential recipient countries: the potential recipients spend costly resources improving governance, while the donor country allocates the fund based on their governance quality. The paper compares two mechanisms: one uses a simple winner-takes-all tournament to award the entire available purse to the country with the best governance; while under the other aid is distributed among countries in proportion to their governance qualities. The paper shows the second mechanism outperforms the first only if competing countries are sufficiently asymmetric. Moreover, the recipient who is most effective in governance – and stands to benefit the most from development assistance – has interests opposite to those of the donor. In addition, the paper shows that if the donor country allocates the fund based on both governance and the levels of poverty, it may result in a poverty trap: the leaders of potential recipient countries deliberately allocate funds away from the poorest so as not to better their position in order to receive more aid.     

Testing the bounds: Empirical behavior of target zone fundamentals

Standard target zone exchange rate models are based on nonlinear functions of unobserved economic fundamentals, which are assumed to be bounded, similarly to the target zone exchange rates themselves. Using a novel estimation and testing strategy, I show how this key but often overlooked assumption may be tested. Empirical results cast doubt on its validity in practice, providing a reason for well-documented empirical difficulties of these models in the literature.     

Estimates of the steady state growth rates for some European countries

This paper estimates the steady state growth rates for the main European countries with an extended version of the Solow (1956) growth model. Total factor productivity is assumed a function of human capital, trade openness and investment ratio. We show that these factors, with some differences, have played an important role to improve the long run growth rates of Italy, Spain, France, UK, and Ireland. A few policies to improve the long-run growth rates for these countries are suggested.     

Do foreigners replace native immigrants? A panel cointegration analysis of internal migration in Italy

This paper examines the impact of the immigration of foreigners on domestic labor mobility. Since David Card's seminal study on the regional labor market impact of the Mariel Boatlift it is controversial whether domestic labor mobility equilibrates economic conditions across regions. However, there is little or no evidence that natives leave destinations where migrants tend to cluster. In this paper we reconcile the existing evidence by taking another route: we analyze whether the immigration of foreigners replaces domestic mobility from poor to rich regions. We focus on Italy, which is characterized by large North-South wage and unemployment differentials, and apply panel cointegration methods. The main finding is that, conditional on unemployment and wage differentials, the presence of foreign workers in the labor force of the destination regions discourages internal labor mobility significantly. As a consequence, spatial correlation studies which use the variance of the foreigner share across regions for identifying the wage and employment effects of immigration, tend to understate the actual impact of foreign immigration.     

A fractionally integrated exponential STAR model applied to the US real effective exchange rate

The aim of this paper is to study the dynamics of the US real effective exchange rate by capturing non-linearity and long-memory features. In this context, we use the family of fractionally integrated STAR (FISTAR) models proposed by van Dijk et al. (van Dijk, D., Franses, P.H., and Paap, R., 2002. A non-linear longmemory model with an application to US unemployment. Journal of Econometrics 110, 135–165.) in the case when the transition function is an exponential function and we develop an estimation procedure. Indeed, these models can take into account processes characterized by several distinct dynamic regimes and persistence phenomena.     

One market, one number? A composite indicator assessment of EU internal market dynamics

We consider the lack of consensus about an appropriate theoretical framework linking sub-indicators as a defining characteristic of composite indicators. This intrinsic feature implies uncertainties about the appropriate normalization and aggregation of the raw data. The two are related: index theory offers some valuable guidelines about their connection. Yet these do not fully solve the basic problem of expert disagreement. We embed such (residual) disagreement in the aggregation method itself. Specifically, we apply an impartial benefit-of-the-doubt weighting procedure, where weight restrictions incorporate the available information on experts’ opinions. We apply this procedure to the dynamic performance assessment of EU Internal Market effects, thereby highlighting its capacity to disaggregate member states’ observed performance shifts into changes relative to benchmarks and performance changes of the benchmarks (i.e. catching up versus genuine progress). Our results indicate that the latter factor is more important in explaining the observed progress.     

AIDS and economic growth: A human capital approach

Using a model that combines growth and health capital equations this study analyses the impact of HIV/AIDS on economic growth. The econometric results indicate that the epidemic's effects have been substantial; in Africa the marginal impact on income per capita of a 1% increase in HIV prevalence rate is minus 0.59%. Even in countries with lower HIV prevalence rates the marginal impacts are non-trivial. Hence while the human and social costs of the HIV/AIDS epidemic are major causes for concern, these results indicate that the macroeconomic affects of the HIV/AIDS epidemic are important.     

Price convergence in the European Union – What has changed?

This paper investigates price convergence in European Union countries using disaggregated price level indices in the period 1999–2016. Our results show that prices of both tradable and nontradable goods had a significantly lower dispersion in 2016 than in 1999. The convergence was faster in the case of countries with price level below the average, which can be interpreted as catching-up. However, further analysis shows that most prices converged only up to 2008. While prices of transport equipment continue to converge across the European Union, several durable consumption categories show price divergence after 2008. We attribute this to the drop in international trade of durable products due to increasing inflation and exchange rates volatility following the global financial crisis. From the monetary policy perspective, the existing price-level gaps, shown in our study, may pose a risk of higher inflation, especially in catching-up economies.     

The economic impact of EU-enlargement: assessing the migration potential

This paper analyzes the determinants of immigration flows to Germany in a time series-cross section framework. The reduced form of a well established theoretical model is estimated for a sample of 17 sending countries and a period covering 1960 to 1994. The estimates are then used to perform out-of-sample forecasts to assess the immigration potential from the Eastern European accession candidates to Germany. These scenarios predict a moderate increase in immigration to Germany, especially for the first round accession candidates. First version received: July 1999/Final version received: July 2000     

What drives the nonlinearity of time series: A frequency perspective

It is well-known that economic and financial time series are characterized by nonlinearities. The literature does not agree, however, on the actual causes of such nonlinearities. In this paper, I investigate whether dynamics at different frequencies present different degree of nonlinearity, and how much they may influence any nonlinearity in the aggregate original series. This paper finds strong evidence in support of the idea that nonlinearities are mostly found at high frequencies.     

Exchange-rate volatility and export performance: Do emerging market economies resemble industrial countries or other developing countries?

Authors who do not distinguish between Emerging Market Economies (EMEs) and other developing countries, find evidence of negative and significant effects of exchange-rate volatility on trade. We investigate the effects of real exchange-rate volatility on exports of ten EMEs and eleven other developing countries that were not classified as EMEs over our estimation period. We use panel-data sets that cover the periods 1980:Q1–2006:Q4 for the EMEs and 1980:Q1–2005:Q4 for the other developing countries. We use two estimation methods — generalized method of moments (GMM) estimation and time-varying-coefficient (TVC) estimation. The TVC procedure removes specification biases from the coefficients, revealing the underlying stable parameters of interest. We obtain similar results as previous authors for only the eleven non-EME developing countries we consider. In contrast, our results for the EMEs do not show a negative and significant effect of exchange-rate volatility on the exports of the countries considered. Our findings suggest that the open capital markets of EMEs may have reduced the effects of exchange-rate fluctuations on exports compared with those effects in the cases of other developing countries.     

Sectoral Productivity in the United States: Recent Developments and the Role of IT

Abstract. This paper introduces new estimates of recent productivity developments in the United States, using an appropriate theoretical framework for aggregating industry multi-factor productivity (MFP) to sectors and the total economy. Our work sheds light on the sources of the continued strong performance of US productivity since 2000. We find that the major sectoral players in the late 1990s pickup were not contributors to the more recent surge in productivity. Rather, striking gains in MFP in the finance and business service sector, a resurgence in MFP growth in the industrial sector, and an end to drops elsewhere more than account for the aggregate acceleration in productivity in recent years. Further, some evidence is found for a link between IT intensity and the recent productivity acceleration.
