This paper analyses the structural characteristics of the food and drink industries and assesses their recent economic performance. Although classified among the less technologically intensive group of British manufacturing industries, the food and drink industries are found to share many of the features of the more technologically intensive group, such as product differentiation, product diversification and advertising intensity. They are also found to have achieved above-average growth in labour and total factor productivity through expansion in size, capital accumulation and shedding of labour.  相似文献

We measure the impact of road and irrigation projects on the livelihoods of households in the poorest and most remote areas of Vietnam using difference-in-difference estimators. We find that both rural road and irrigation projects help local households improve the access to safe water and welfare measured by a wealth index. The impact of irrigation projects is found to be larger than the impact of road projects. We also find heterogeneous impacts of road and irrigation projects. Households with higher levels of education tend to benefit more from road projects, while households with lower levels of education are likely to benefit more from irrigation projects.  相似文献

This paper examines the effect of attending a Catholic high school on educational outcomes. The statistical analysis is based on data obtained from the US National Educational Longitudinal Study. Using propensity score matching methods to control for selection bias, we find that Catholic schooling improves maths test scores, with stronger effects for males than for females, but appears to have little effect (if any) on reading scores. Catholic schooling also raises high school graduation rates and substantially increases the likelihood of enrolment in a 4‐year college. Use of the difference‐in‐difference method suggests that the effect of Catholic schooling on changes in maths scores is more muted, though still statistically significant.  相似文献

It is shown that the stochastic investment rule for the price-setting monopolist facing random demand differs from the deterministic rule, due to the presence of the covariance of the marginal utility of profits and the MRTS between capital and labor. For the risk-neutral quantity-setting monopolist, the optimal current investment under random demand is shown to be greater than that under deterministic conditions, given that production technology is of the Cobb-Douglas type with constant returns to scale. When random wages and prices follow first-order autoregressive schemes, the risk-neutral competitive firm's current investment level is shown to be at least equal to that under certainty.  相似文献

Zusammenfassung Die Identifikation der Lorenzkurve durch Lorenzkoeffizienten. — Der aus der Lorenzkurve abgeleitete Gini-Koeffizient vermittelt einen guten Eindruck von dem Ma\ an Ungleichheit. W?hrend sich jedoch eine Lorenzkurve auf den Gini-Koeffizienten im Verh?ltnis eins zu eins übertragen l?\t, entspricht — in der entgegengesetzten Richtung — ein Gini-Koeffizient mehreren Lorenzkurven. In dieser Untersuchung wird die Lorenzkurve in einzelne Abschnitte aufgeteilt. Dann wird jedem Abschnitt ein gewogener Lorenz-Koeffizient zugeordnet, wodurch es m?glich wird, Lorenzkurven mit identischen Gini-Koeffizienten zu unterscheiden. Die Verbindung zwischen jedem Kurvenpaar kann aufgehoben werden, indem man von Abschnitt zu Abschnitt die jeweiligen Lorenz-Koeffizienten vergleicht. Ein empirisches Beispiel ist in dem Artikel enthalten.
Résumé L’identification de la courbe de Lorenz par le coefficient de Lorenz. — Le coefficient de Gini dérivé de la courbe de Lorenz exprime un degré considérable de sens intuitif pour la mesure de l’inégalité. La reproduction de la courbe de Lorenz en coefficient de Gini est cependant dans le rapport un à un, celle du coefficient de Gini en courbe de Lorenz un à beaucoup. Cette étude veut partager la courbe de Lorenz en piéces détachées. Un sous-coefficient pondéré de Lorenz est associé avec chaque partie, une méthode qui permet à différencier les courbes de Lorenz avec des coefficients identiques de Gini. Le lien entre chaque paire de courbes peut être détaché si on part d’une comparaison de chaque sous-coefficient de Lorenz de partie à partie. L’auteur fournit une application empirique.

Resumen Identificación de la curva de Lorenz por medio del coeficiente de Lorenz. — El coeficiente de Gini derivado de la curva de Lorenz transmite sentimientos intuitivos considerables para la medida de desigualdad. Sin embargo, el desdibujamiento de la curva de Lorenz hacia el coeficiente de Gini es uno a uno y el del coeficiente de Gini hacia la curva de Lorenz de uno a muchas veces. En este estudio se divide la curva de Lorenz en partes. Un sub-coeficiente de Lorenz se asocia con cada parte permitiéndonos diferenciar curvas de Lorenz con idénticos coeficientes de Gini. La unión entre cualquier par se puede quebrar procediendo a comparar cada sub-coeficiente de Lorenz de parte en parte. Se presenta una aplicación empírica.

A differential money demand equation is used to estimate the weight given to each commodity group in the price index which transforms nominal into real cash balances. The results indicate that food receives the largest weight and that the CPI is a good proxy for the true deflator.  相似文献

ABSTRACT

Attention has become an area of major interest in marketing research as a dependent or moderating variable. In this article, we argue for respondent attention as a pivotal part of any consumer psychology research protocol and highlight the risks of not incorporating realistic attention components into research design. We propose four areas where this approach can help the external validity of consumer psychology research. Our recommendations include accounting for variability in the baseline attention levels; smart use of distractions; allowing for variability in attention over the task and avoiding attention leading/assumptive questions.  相似文献

This study employs the fractional multinomial logit setting proposed by Papke and Wooldridge (1996) to examine factors driving the choice among nonbank private (144A) debt, bank loans and public debt made by 988 nonfinancial firms during 1993–2007. We document that the majority of firm-level factors have persistent effects on corporate outstanding debt mix across economic conditions. We also highlight the importance of macroeconomic variables on firms’ borrowing decisions as predicted by Diamond (1991). Finally, we document a substitution effect among debt financing sources due to credit rating downgrades, which is inconsistent with Rauh and Sufi (2010).  相似文献

This paper analyzes the relationship between government expenditure, tax on returns to assets, public debt, and growth in an endogenous growth model. Public debt is composed of two components, domestic debt and external debt. We show conditions for existence, uniqueness, and multiplicity of the steady states. More precisely, existence of steady state requires a sufficiently high productivity and a sufficiently low tax on returns to assets. We also provide the effects of an increase in the tax rate on returns to assets on the steady state. In particular, the relation between public spending and the tax rate has a bell shape. Domestic debt unambiguously increases with tax whereas external debt displays an inverted U‐shaped curve. A high tax rate leads to a reallocation of public debt in favor of domestic debt (to the detriment of external debt). The effect of taxation on consumption (and production) also displays a nonlinear pattern when the output elasticity of capital is lower than unity (the effect is monotonously increasing if this elasticity is unity). We also derive the conditions under which a tax increase can boost or reduce the balanced growth rate.  相似文献
