Indexation of UNCTAD core commodity prices by buffer stocks or export quotas?: A comparison of the benefits for two developing economies

General equilibrium models are used to study the resource allocative and income implications for the Ivory Coast and Kenya of indexation of agricultural commodity prices. Two indexation methods are investigated, (i) buffer stock transactions, and (ii) export quota entitlements. The results suggest that there are efficiency losses associated with the buffer stock option which reduce the GDP gains below that indicated by the pure terms of trade gains. Efficiency gains associated with the export quota method however result in GDP increases above those indicated by the pure terms of trade gains.     

Determinants of corporate borrowing: A note

In his article Determinants of Corporate Borrowing, Myers (1977) says that it is not guaranteed that the maximum value of the firm is reached before the maximum value of the debt is utilized in the case in which the interest payment is fully tax deductible, but the tax shield is lost if the firm goes bankrupt. I have shown here that even in such a case the maximum value of the firm will always be achieved before the maximum available debt is utilized.     

On testing the dimensionality of regression coefficients

In this paper, the distribution of a statistic based on the likelihood ratio method for testing the dimensionality of regression coefficients has been derived. The method of integration over alternate variables has been used to derive the results.     

South Africa’s monetary policy independence: evidence from a Global New-Keynesian DSGE model

We study the response of South African monetary policy decisions to foreign monetary policy shocks. We estimate the extent of foreign monetary policy pass through by augmenting standard Taylor rules and comparing the results within the context of a Global New-Keynesian Dynamic Stochastic General Equilibrium (DSGE) model. The general equilibrium model captures important spill-over effects that would otherwise have been ignored in a single equation set-up. The results show that the relationship between foreign monetary policy shocks and South African interest rates is complicated – South Africa does not import foreign monetary policy directly, but is still affected. Except for the US, an increase in foreign interest rates leads to a decrease in South African interest rates – highlighting the complex channels that the monetary policy authority has to monitor outside of its economy.     

Convergence in Income Inequality: Further Evidence from the Club Clustering Methodology across States in the U.S.

This paper contributes to the sparse literature on inequality convergence by empirically testing convergence across states in the U.S. This sample period encompasses a series of different periods that the existing literature discusses -- the Great Depression (1929–1944), the Great Compression (1945–1979), the Great Divergence (1980-present), the Great Moderation (1982–2007), and the Great Recession (2007–2009). This paper implements the relatively new method of panel convergence testing, recommended by Phillips and Sul (2007). This method examines the club convergence hypothesis, which argues that certain countries, states, sectors, or regions belong to a club that moves from disequilibrium positions to their club-specific steady-state positions. We find strong support for convergence through the late 1970s and early 1980s, and then evidence of divergence. The divergence, however, moves the dispersion of inequality measures across states only a fraction of the way back to their levels in the early part of the twentieth century.     

Development of Scale to Measure Objectives-Oriented Investment Behavior

Abstract

While planning for personal finances, researchers recommend investors adapting systematically planned investment behaviors that align investments with their financial objectives; however, they fail to provide a scale for the measurement of such behaviors. Therefore, this study develops a scale, conducts exploratory and confirmatory factor analysis, and provides evidence of the reliability of the scale measuring objectives-oriented investment behaviors. Examining a cross-sectional data of 448 investors collected through the new scale, the study finds that a majority of the investors’ do not follow objectives-oriented behavior. The results inform that the selection of investment avenues and allocation of funds were not aligned with investors’ financial objectives.     

An econometric analysis of the world zinc market

A fairly detailed market form of econometric model is built, based on the technological, behavioral and institutional features of the world zinc industry. An estimated version of the model indicates different systems of lag responses in the structures of demand and supply to the price of zinc, a very poor substitutability on the demand side, free market price as a long-run equilibrator for the U.S. producers' price, and an important influence of the U.S. interventions on the world market. The model meets reasonably well the predictability criterion based on the technique of dynamic simulation. The performance properties of the world zinc industry, analysed through dynamic multiplier simulation technique, show that the industry exhibits a reasonably, stable market environment to the exogenous disturbances such as an increase in the activity levels of consumers and variations in the prices of substitutes. It is, however, quite sensitive to technological changes in the consumer industries. The stockpile policy of the U.S. Government does not seem to be properly geared to its objectives and, in general, it seems to have restricted the development of the industry as a whole.     

Reconsidering the welfare cost of inflation in the US: a nonparametric estimation of the nonlinear long-run money-demand equation using projection pursuit regressions

This paper, first, estimates the appropriate, log–log or semi-log, linear long-run money-demand relationship capturing the behavior US money demand over the period of 1980:Q1–2010:Q4, using the standard linear cointegration procedures found in the literature, and the corresponding nonparametric version of the same based on projection pursuit regression (PPR) methods. We then, compare the resulting welfare costs of inflation obtained from the linear and nonlinear money-demand cointegrating equations. We make the following observations: (i) the appropriate money-demand relationship for the period of 1980:Q1–2010:Q4 is captured by a semi-log function; (ii) based on the estimation of semi-log cointegrating equations, the welfare cost of inflation was found to at the most lie between 0.0131 % of GDP and 0.2186 % of GDP for inflation rates between 0 and 10 %, and; (iii) in comparison, the welfare cost of inflation obtained from the semi-log non-linear long-run money-demand function, derived using the PPR method, for 0–10 % of inflation ranges between 0.4930 and 1.9468 % of GDP. However, the standard errors associated with the welfare cost estimates obtained from PPR relative to the linear models tend to indicate that the nonlinear money demand provides more precise estimates of the welfare costs primarily for higher rates of inflation.     

医保改革面临挑战

当前,许多国家仍存在医疗服务可得性差、医疗成本高昂、公共卫生支出效率低下等问题,医保改革面临重大挑战。医保改革目标存在两难—既要改善人们的健康状况,又要控制支出成本,因而提高公共卫生支出效率是改善社会健康状况的最优选择。各国政府的干预形式和公共卫生支出水平因国别、时间等的不同而变化。财政状况较好的新兴经济体需在保证财政可持续的前提下扩大基本医保覆盖面;发达经济体则应注重提升公共卫生支出的效率并限制支出增长速度。     

Exploring antecedents of healthy food choices: an Indian experience

Label information on food items is seen as a tool to facilitate better choices. Merely, provision of label information may not lead to the desired outcome. Comprehension and processing of label information during consumer decision making is crucial for better food choices. Based on the primary data obtained from 150 consumers of pre‐packaged food items, the research proposes a conceptual model for healthier food choices. Previously, a number studies related to consumer decision making have employed ‘label reading’ and ‘label use’ interchangeably. Present research advocates that label reading does not amount to label use. Findings from ordered probit model and path analysis suggest that comprehension of label information leads to increase in its perceived usefulness. Further, increased perceived usefulness facilitates better food choice. Instances of better food choices can be maximized by enhancing perceived usefulness and comprehension of label information through educational and awareness campaigns, especially in context of developing countries such as India.
