Global environmental problems are often assumed to imply extensive inefficiencies since there is no global authority corresponding to the government at a national level. This paper shows, on the contrary, that rich countries in a free unregulated market may still undertake globally efficient...

In a signalling model of conformity, we demonstrate that naïve observers, those that take actions at face value, constrain the set of actions that can possibly be social norms. With rational observers many actions can be norms, but with naïve observers only actions close to that preferred by...

A growing literature in economics examines the development of preferences among children and adolescents. We combine a repeated dictator game with treatments that either provides participants with information about the average behavior of others or not. In a sample of 384 children aged 5-17, we...

Complementing market-based policy instruments with conflict analysis approaches provides a wider understanding of market situations and allows to identify minimal requirements regarding needs, power and conflict dynamics. If these are not met, a market cannot be successfully introduced or a...

The aim of the present paper is to examine the existence and patterns of systematic within-country inequalities in effective land rights in Rwanda. The results of empirical estimations drawing on data on the land tenure arrangements of over 5,000 Rwandan households indeed suggest systematic...

This study is about institution building with limited resources. Through a case study of the establishment of a supreme audit institution (SAI) in Rwanda, we examine the tensions between institutional first-best benchmarks and local operational constraints in a developing country...

In this paper we assume that choice of commodities at the individual (household) level is made inside the budget set and that the choice can be described by a probability density function. We prove that law of demand()0xExpis valid for one(x) or two choice variables (x, y)*. The law of...

This paper looks at the fuel choice of urban households in major Ethiopian cities, using panel data collected in 2000 and 2004. It examines use of multiple fuels by households in some detail, a topic not much explored in the household fuel-choice literature in general, and in sub-Saharan Africa...

In this paper we use some(even a convex) probabilistic frequency functions in two choice variables defined over the budget set” box” and calculate the expected demand to study its properties The expected demands have own price negativity , are normal goods and are homogeneous of degree...
