This paper provides an overview on the impacts of food aid. We consider its effects on consumption, nutrition, food markets and labour supply, as well as the extent to which it exacerbates or mitigates conflict. We also consider the comparative evidence on alternatives to food aid including...

The rate of deforestation in Africa is of paramount concern not only to the future of Africa, but also to the world. This study uses country-level data to model changes in forest area over an 18 year period (1990-2007) in 35 African countries and investigates the role played by important...

This study aims to estimate electricity demand functions in Japan's industrial and commercial sectors. We adopt data from the Energy Consumption Statistics by Prefecture by the Ministry of Economy, Trade and Industry, Japan, to delineate the demand between the industrial and commercial sector....

The problem of instrument proliferation and its consequences (overfitting of endogenous variables, bias of estimates, weakening of Sargan/Hansen test) are well known. The literature provides little guidance on how many instruments is too many. It is common practice to report the instrument count...

The problem of instrument proliferation and its consequences (overfitting of the endogenous explanatory variables, biased IV and GMM estimators, weakening of the power of the overidentification tests) are well known. This paper introduces a statistical method to reduce the instrument count. The...

OTT-messenger such as facebook, WhatsApp have gained wide popularity among mobile users while traffic of text messaging has been in strong decline in several countries. This work is the first to provide an empirical analysis how consumption of OTT-messengers affects demand for text messaging and...

This study estimates the impact of interprovincial and international migration on interprovincial trade using annual data from 1981- 2016 for Canadian provinces. We apply both the gravity and the spatial trade models for estimation using a number of panel estimators. We find that the endogeneity...

Literature on residential water demand is rich, however, there are few estimates of price and income elasticities for Central and Eastern Europe and for countries undergoing economic or political transitions. To cover this gap, we estimate residential water demand in the Czech Republic - which...

This paper reviews recent developments in nonparametric identi.cation of mea- surement error models and their applications in applied microeconomics, in particular, in empirical industrial organization and labor economics. Measurement error models describe mappings from a latent distribution to...

This paper estimates demand for residential solar photovoltaic (PV) systems using a new approach to address three empirical challenges that often arise with count data: excess zeros, unobserved heterogeneity, and endogeneity of price. Our results imply a price elasticity of demand for solar PV...
