Econometric models wishing to estimate relevant parameters for agricultural policy analysis are increasingly relying on unbalanced panels of farm-level data. Since in the agricultural economics literature such models have often been estimated through simplified approaches, in this paper we try to verify whether the adoption of more sophisticated panel data techniques may impact the estimation r...

BACKGROUND In this paper we investigate the causal relationship between suicide and a variety of socioeconomic variables. We use a panel data set of Canadian provinces, 2000 - 2008, and a set of recent panel econometric techniques in order to account for a variety of statistical specification issues. RESULTS We find that the social and economic determinants of suicide in Canadian provinces va...

This paper investigates the relationship between economic development and female labor force participation in the Middle East and North Africa (MENA). Using a panel data set of 20 countries in the region for the period of 1990-2012, I develop an econometric model that tests the U-shape hypothesis. This study builds upon previous literature examining the U-shape hypothesis in time series studies...

This article presents one of the first large-sample empirical analyses of the impact of services on the business models (i.e. the financial performance) of product firms. We build upon existing and recent literature in technology management, economics, and service operations in order to propose and test hypotheses regarding the relationship between level of service revenues and operating profit...

This paper applies univariate and panel data unit root tests to annual panel data for 182 countries over the period 1979-2000 to examine the stationarity properties of per capita energy consumption. The univariate unit root test can only reject the unit root null for 29 per cent of the countries at the 10 per cent level or better without a trend and 37 per cent of the countries at the 10 per ce...

This paper analyzes the delays and therefore the unpredictability of foreign aid in Africa. As many African countries are dependant to foreign aid, it’s important to understand to what extent aid delays matters for the absorptive capacity and therefore influences aid effectiveness. As the aid literature on absorptive capacity was mainly focused on dutch disease, decreasing returns and instituti...

Many theories in political science predict the spatial clustering of similar behaviors among neighboring units of observation. This spatial autocorrelation poses implications for both inference and modeling that are distinct from the more familiar serial dependence in time series analysis. In this paper, I examine how political scientists can diagnose and model the spatial dependence that is pr...

We introduce a regression-based gravity model for commodity flows between 35 regions in Austria. We incorporate information regarding the highway network into the spatial connectivity structure of the spatial autoregressive econometric model. We find that our approach produces improved model fit and higher likelihood values. The model accounts for spatial dependence in the origin-destination fl...

This paper investigates spatial panel data models with a space-time …lter in disturbances. We consider their estimation by both …xed e¤ects and random e¤ects speci…cations. With a between equation properly de…ned, the di¤erence of the random vs. …xed e¤ects models can be highlighted. We show that the random e¤ects estimate is a pooling of the within and between estimates. A Hausman type speci…c...

This paper gives a selective review on the recent developments of nonparametric and semiparametric panel data models. We focus on the conventional panel data models with one-way error component structure, partially linear panel data models, varying coe¢ cient panel data models, nonparametric panel data models with multi-factor error structure, and nonseparable nonparametric panel data models. F...
