This article estimates the price elasticities of the demand for mobile telephone calls and the demand for messages for Portugal. We use a panel of individual level data. In order to account for the unobserved individual heterogeneity and for the data censoring, we estimate a Tobit model for panel data with individual random effects. The demand for calls and the demand for messages are inelastic...

The purpose of this paper is to investigate the performance of Turkish (TR) commercial banking sector. We evaluate the technical efficiency of individual TR banks using the nonparametric frontier methodology, the Data Envelopment Analysis (DEA). To investigate the determinants of efficiency, we use the Tobit model. This analysis aims to explain the variation in calculated efficiencies to a set ...

Using a new dataset for 41 German non-governmental organizations (NGOs), we analyze the allocation of NGO aid across recipient countries in a Tobit regression framework. By identifying for each NGO the degree of public refinancing, we address the largely unresolved issue of whether financial dependence on the government impairs the targeting of NGO aid.

The aid allocation literature explores the motives behind development aid assistance. This literature is enormous, yet surprisingly, the extant empirical studies have in the main only focused on the motives of established donors. Consequently, relatively little is known of the motives of new donors. This paper explores the aid allocation motives of three relatively new DAC donors: Greece, Luxem...

Modernization and commercialization of the smallholder agricultural sector provides the stimulus and impetus to reducing food insecurity in developing countries. This study seeks to fill the gaps in the literature particularly by comprehensive conceptualization of the drivers of commercialization at a household level and across different socioeconomic and agro-ecological zonation in the wake of...
