The History of the Dirichlet and Liouville Distributions

The Dirichlet distributions have long been the subject of intense scrutiny in statistics and probability. Despite the enormous interest in, and wide-ranging applications of, these distributions, little appears to be known about their history. In this article we review the development of the Dirichlet distributions and their companions, the Liouville distributions. After reviewing some integral formulas of Dirichlet and Liouville, we survey the theory and applications of these distributions in statistics.     

Policy Effectiveness and the Slopes of IS and LM Curves: A Graphical Analysis

In contrast to Michael Lovell's argument, this comment argues that the lack of computer-aided instruction (CAI) materials does not result from the public-good nature of educational software but from a lack of demand for CAI materials.     

Visualizing the gains from trade,mid-1870s to 1962

Abstract

This paper explores the various personal and intellectual links between Edmund Husserl, Rudolf and Walter Eucken. Our interdisciplinary approach gives an insight into Husserl's transcendental phenomenology, Walter Eucken's Ordoliberalism as well as in the interdependency between phenomenology and economics for which Rudolf Eucken's philosophy of intellectual life plays an important role. Particular affiliations between phenomenology and economics can be found in the following topics: epistemology, the idea of man, the comprehension of liberty and the importance of legal or social orders, institutional rules and frameworks of regulations.     

Migrants’ international transfers and educational expenditure

The primary objective of this article is to cast some light upon the relationship between education expenditure and the volume of remittances sent to Albania from abroad by international migrants. To assess the existence of an education enhancing effect of remittances, an Engel curve framework is used. In addition, quintile regression analysis is employed to investigate whether migrants’ remittances have a differentiated effect on various quantiles of the conditional distribution of education consumption. The two main empirical findings are that household income has a positive and well‐determined impact on education expenditure, whereas international transfers do not influence education spending.     

Demand Analysis of Meat in Malaysia

One distinct change in Malaysians' food consumption behavior has been the preference toward meat products. Thus it is meaningful to gain insight of meat consumption patterns. As the market becomes increasingly market-led, information on current meat consumption patterns is required to assess how they are likely to change as prices and incomes change. This study attempts to provide a better understanding of demand for meat products in Malaysia. By utilizing data from Household Expenditure Survey 2004/2005, Engel curve analysis was conducted to derive income elasticities of meat products from QUAIDS model. The estimated income elasticities show that current food consumption patterns are showing signs of convergence toward a Western diet, exhibiting tendency for preference toward red meats (mutton and beef) over white meats (poultry and pork). The estimated elastic own-price elasticities indicate that Malaysian consumers are sensitive to the change in prices of the meat products, with other things remain constant.     

Affine multiple yield curve models

We provide a general and tractable framework under which all multiple yield curve modeling approaches based on affine processes, be it short rate, Libor market, or Heath–Jarrow–Morton modeling, can be consolidated. We model a numéraire process and multiplicative spreads between Libor rates and simply compounded overnight indexed swap rates as functions of an underlying affine process. Besides allowing for ordered spreads and an exact fit to the initially observed term structures, this general framework leads to tractable valuation formulas for caplets and swaptions and embeds all existing multicurve affine models. The proposed approach also gives rise to new developments, such as a short rate type model driven by a Wishart process, for which we derive a closed‐form pricing formula for caplets. The empirical performance of two specifications of our framework is illustrated by calibration to market data.     

The carbon Kuznets curve: A cloudy picture emitted by bad econometrics?

We discuss several major econometric problems that have been ignored in the empirical environmental Kuznets curve (EKC) literature thus far. These are: First, the use of nonlinear transformations of integrated regressors and second, in a panel context, cross-sectional dependence in the data. Both problems fundamentally invalidate the use of widely applied time series and panel unit root and cointegration techniques. We use the important special case of the relationship between GDP and CO₂ (and SO₂) emissions to show and discuss in detail that the seemingly strong evidence for an inverted U-shaped relationship between these variables obtained with commonly used methods is entirely spurious and vanishes when resorting to estimation strategies that take the discussed problems into account.     

Deriving the Engel Curve: Pierre Bourdieu and the Social Critique of Maslow's Hierarchy of Needs

In Post Keynesian Economics, theorists have sought an alternative to neoclassical choice theory by turning to Maslow's hierarchy of needs (Pasinetti 1981 Pasinetti LL 1981 Structural Change and Economic Growth Cambridge: Cambridge University Press  , Lavoie 1992 Lavoie M 1992 Foundations of Post-Keynesian Economic Analysis London: Edward Elgar  ). Instead of each individual surveying a complete choice set, individuals prioritize (basic) physiological needs, moving with increasing incomes to satisfy safety and social needs, through to the higher needs associated with self-actualization. This framework provides a theoretical foundation for the Engel curve, since as incomes increase consumers become satiated when particular needs are satisfied. As an alternative to the neoclassical preoccupation with prices and substitution, a Post Keynesian theory of consumption has been formulated with income effects as the cornerstone. The main problem with Maslow's approach is that individual needs are innate, so that questions of social interaction and culture are seriously downgraded. In this article, the social theory of Pierre Bourdieu is offered as an alternative to the Maslow approach, providing the basis for a social critique of consumerism and an alternative evolutionary theory of consumption. In this approach, the structure of the social hierarchy both constrains the consumption of lower social strata and leads to subtle, less conspicuous consumption patterns at the top of the social hierarchy: a scenario that could provide a social foundation to the Engel curve.     

Heterogeneity in Consumer Demands and the Income Effect: Evidence from Panel Data

This paper uses unique Spanish panel data on household expenditures to test whether unobservable heterogeneity in household demands (taste, etc.) is correlated with total expenditures (income). The main finding is that tastes are indeed correlated with income for about half of the goods considered, implying that cross‐sectional estimates of income elasticities for these goods are biased. The goods are the following: food eaten outside home, alcohol and tobacco, transportation, and energy. The elasticity of alcohol and tobacco is more than halved when taking unobserved heterogeneity into account. For transportation, the bias is sufficiently large to misclassify the good as a luxury.
