We examine the choice of policy instrument price, quantity, or a mix of the two when two pollutants are regulated and firms’ abatement costs are private information. A key parameter that affects this choice is the technological externality between the abatement efforts involved, i.e., whether...

In this paper we assume that choice of commodities at the individual (household) level is made in the budget set and that the choice can be described by a probability density function. We prove that negativity (()0xExp<) is valid for one(x) or two choice variables (x, y) (No Giffen good).Negativity at the market level is valid by summation. The expected demand functions are homogeneous of degree zero in prices and income. We use general positive continuous functions f(x), f(x, y) defined on the bounded budget set. We transform them into probability density functions to calculate E(x) and prove negativity. The present approach use simple assumptions and is descriptive in its nature. Any choice behaviour that can be described by a continuous density function gives the above results. (,,)xyppm Why not keep descriptions as simple as possible?<p>

The aim of this paper is to examine the role of individual resource endowments for explaining individual and group variation in African political participation. Drawing on new data for more than 27 000 respondents in 20 emerging African democracies, the empirical findings suggest surprisingly...

This paper addresses the issue of ordering effects in choice experiments, and in particular how learning processes potentially affect respondents’ stated preferences in a sequence of choice sets. In a case study concerning food quality attributes of chicken breast filets, we find evidence of...

Using a choice experiment, we investigated preferences for distributing the economic burden of decreasing CO2 emissions in the two largest CO2-emitting countries: the United States and China. We asked respondents about their preferences for four burden-sharing rules to reduce CO2 emissions...

Hypothetical bias is one of the main issues bedeviling the field of nonmarket valuation. The general criticism is that survey responses reflect how people would like to behave, rather than how they actually behave. In our study of climate change and emissions reductions, we took advantage of the...

During the global food crisis, Ethiopia experienced an unprecedented increase in inflation, among the highest in Africa. Using monthly data over the past decade, we estimate models of inflation to identify the importance of the factors contributing to CPI inflation and three of its major...

We studied whether relative income has an impact on subjective well-being among extremely poor people. Contrary to the findings in developed countries, we cannot reject the hypothesis that relative income has no impact on subjective well-being in rural areas of northern Ethiopia.<p>

The pioneers of Swedish economics at the end of the 19th and beginning of the 20th century were to a large extent influenced by German ideas and German academic life. They went to Germany to study, and their scientific works were usually written in German or Swedish. During the 20th century the...

Politics and economics are inextricably linked. Government establishes and enforces the rules of the game for the economy, thereby determining not only how much wealth is created, but also how wealth is distributed across society. The primary question of political economy is easily stated: for...
