The Conway-Maxwell-Poisson distribution: distributional theory and approximation

The Conway-Maxwell-Poisson (CMP) distribution is a natural two-parameter generalisation of the Poisson distribution which has received some attention in the statistics literature in recent years by offering flexible generalisations of some well-known models. In this work, we begin by establishing some properties of both the CMP distribution and an analogous generalisation of the binomial distribution, which we refer to as the CMB distribution. We also consider some convergence results and approximations, including a bound on the total variation distance between a CMB distribution and the corresponding CMP limit.Comment: 26 page

Cross-National Trends in Earnings Instability and Earnings Inequality

Changes in inequality of yearly earnings can arise from changes in the distribution of lifetime earnings (permanent changes) and changes in the stability of earnings (transitory changes). Past research has found increases in both components in the United States over the past several decades. We extend this literature by comparing the United States with Germany and Great Britain. We use data from the Cross-National Equivalent Files (Cornell University) to document trends in cross-sectional and long-run earnings inequality. These data enable us to examine earnings dynamics during the years 1979-1996 for the United States, 1983-1997 for Germany, and 1990-1997 for Great Britain. Despite differences in labor market structure, our descriptive models reveal similar basic patterns of earnings mobility and dynamics in these countries. We then apply a method of moments approach to estimate the parameters of a heterogeneous growth model of permanent and transitory earnings. The results indicate that although there are substantial differences in overall cross-sectional inequality across these countries, the persistent component of earnings inequality was quite similar in each in the 1990searnings mobility, inequality, comparative

Changing Family Behavior and the U.S. Income Distribution

The trend toward increasing family income inequality in the U.S. over the past several decades is well documented. Among possible explanations for this increase are rising inequality in individual earnings, changes in family labor supply decisions, and changes in family structure and living arrangements. We analyze the contribution of the latter two factors to rising family income inequality during the 1980s using conditionally weighted density estimation, a semiparametric decomposition technique recently pioneered and applied to assess the causes of rising earnings inequality (DiNardo, Fortin, and Lemieux 1996). This technique enables estimation of the impact of the modeled factors on the complete distribution of income. We use data from the March Current Population Surveys for the years 1980 and 1990, which yield family income information for the years 1979 and 1989. The primary effect of both changing family structure and changes in wives' labor force participation was on the midpoint of the family income distribution. The effect of changing family structure on rising inequality was small over this period, primarily because the net change in family structure was small. However, the increase in wives' labor force participation explains about 10 to 25 percent of the increase in family income inequality.

Inequality and poverty in the United States: the effects of changing family behavior and rising wage dispersion

The trend toward increasing inequality in family income in the United States since the late 1960s is well documented. Among key possible explanations for this increase are rising dispersion in individual earnings, changes in female labor supply decisions, and changes in family composition and living arrangements. We analyze the contribution of these factors to changes in family income inequality and poverty during the years 1969-1998, focusing on labor supply and family structure as behavioral changes but accounting also for changes in the distribution of male earnings. Our analyses rely on conditionally weighted density estimation, a semiparametric decomposition technique recently developed by DiNardo, Fortin, and Lemieux (1996). We also use a relatively novel rank-based distributional exchange to assess the effects of changes in the distribution of male earnings. ; In our empirical work, we first analyze changes between 1969 and 1989, which corresponds roughly to the period of rising inequality that has been the focus of previous work. Our results indicate that rising dispersion of male earnings and the decline of traditional forms of family structure respectively explain up to about three-fourths and about one-half of rising inequality in family income during this period. The impact of changing family structure was most pronounced in the lower half of the distribution. In contrast, the increase in female labor force participation offset rising inequality to some degree, mainly in the upper half of the distribution, although its impact has moved down the distribution over time. In extending the analyses to the 1990s, we find that the rate at which inequality grew slowed after 1989, but the explanatory factors continued to have substantial effects. In each decade, the effects of the explanatory factors on poverty were especially large and followed a pattern similar to that for inequality.Poverty ; Income distribution ; Income

On Democratic Personalities

In Part I, I describe and discuss the ideal traits of a democratic personality, note the contribution of education to the acquisition of these traits, and describe other immature traits of personality that impede or preclude the emergence of a democratic personality. In Part II, I note how the traits of a democratic personality are or are not acquired through the processes of identity formation in late adolescence and early adulthood. Finally, I contrast the ideal traits of a democratic personality with other traits that can frustrate attempts to develop a democracy but which can contribute to successful adaptation in some relations of exchange. I conclude by offering a comment on the prospects for democracy in America

THE EFFECTS OF VISUAL IMPAIRMENT ON COMPETITION SWIM PERFORMANCE

Several factors contribute to successful swim performance, but how are they affected by impaired vision? The purpose of this study was to examine the relationship between degree of visual impairment and performance variables during the 100m freestyle and backstroke events in Paralympic swimmers and to compare the performances with those of Olympic swimmers. A competition video analysis conducted at the 1996 Paralympic Games showed that performance tends to decrease in all aspects of the race with increasing visual impairment. Continued competition race analyses and delivery of results to the coaches will help in strengthening the competition of Paralympic swimming

GEOPHYSICAL EXPLORATIONS ON AND NEAR THE ISMENION HILL, THEBES, GREECE, 2011

Το άρθρο αυτό παρουσιάζει τις πρώτες κοινές έρευνες στη Θήβα, στην περιοχή του ναού του Απόλλωνος Ισμηνίου, που κρίθηκαν επιβεβλημένες, πριν από την υποβολή μιας ολοκληρωμένης και τεκμηριωμένης πρότασης Συνεργασίας, για τη διενέργεια εργασιών πεδίου και πιό συγκεκριμένα ανασκαφών. Οι έρευνες αυτές έλαβαν χώρα το καλοκαίρι του 2011, μετά από ευγενική πρόσκληση του Διευθυντή τότε ένατης Εφορείας, Καθηγητή κυρίου Βασίλειου Αραβαντινού, που χρονολογείται το 2010. Σκοπός μας ήταν ωα αναλάβουμε μαζί την προσπάυεια διερεύνησης τοπογραφικών και αρχαιολογικών ζητημάτων, σχετικών με την παλαιά ανασκαφή του Ισμηνίου και τη νεώτερη του Ηρακλείου των Θηβών
