A general equilibrium model of the incidence of corporation income tax under uncertainty

In this paper we investigate the incidence of the corporation income tax in terms of a two-sector, general equilibrium model, where production decisions are made under uncertainty. The conventional result, derived originally by Harberger (1962), is that if the corporate sector is the capital-intensive sector, then capital must bear a greater burden of the tax, in proportion to its initial share in national income, than labor. This result continues to hold unambiguously under uncertainty only if the relative and the absolute risk aversion of the corporations are non- increasing in profits. Otherwise, the Harberger result may not hold.     

Attitudinal effects of ad-evoked moods and emotions: The moderating role of motivation

The role of the moods and emotions evoked by advertisements in shaping the amount and valence of cognitive elaboration, as well as consumer brand attitudes, has recently begun to elicit research interest. It is shown that moods and emotions appear to influence brand attitudes more in low personal relevance (“low motivational involvement”) situations than under high-motivation conditions, by suppressing counterargumentation more in such low motivation situations. Implications are discussed for advertising theory and practice © 1994 John Wiley & Sons, Inc.     

Technology and Firm Size-Wage Differentials in Colombia, Mexico, and Taiwan (China)

In many economies, studies have found large wage differentialsnot accounted for by work force characteristics, collectivebargaining, or market power. Researchers attribute these differentialsto either unobserved worker quality or pay incentives designedto elicit worker effort. This article finds empirical supportfor an alternative explanation: These wage differentials resultfrom firms' technology-generating activities. Using firm-leveldata from Colombia, Mexico, and Taiwan (China), the articlecompares the effects of research and development, worker training,and exports by employers on the wages of skilled and unskilledworkers. The results suggest that technology investments leadto large wage premiums for skilled workers but not for unskilledworkers. These wage premiums are primarily the result of investmentsin research and development and in training, while exportingis relatively less important except in Colombia.     

Teacher unions, teacher pay and student performance in India: A pupil fixed effects approach

This paper examines the relationship between teacher unionization, student achievement and teachers' pay using a cross-section of data from private schools in India. We use differences in student mark across subjects to identify within-pupil variation in achievement and find that union membership of the teacher is associated with reduced pupil achievement. We find no evidence this could be due to the unobservables not controlled for by this procedure. A school fixed effects equation of teacher pay shows that union membership raises pay and in this case too we find that remaining unobservables are unlikely to explain this outcome. We discuss the policy implications of the findings and show that the effectiveness of teacher credentials in improving teacher performance is linked to unionization.     

Race and the Incidence of Unemployment in South Africa

South Africa's unemployment rate is one of the highest in the world, and it has important distributional implications. The paper examines both entry into and duration of unemployment using data for the mid‐1990s. A probit model of unemployment shows an important role for race, education, age, gender, home‐ownership, location, and numerous other variables, all of which have plausible explanations. The large race gap in unemployment is explored further by means of a decomposition analysis akin to that normally used to analyze wage discrimination. There remains a substantial residual which might represent unobserved characteristics, such as quality of education, or discrimination.     

Tariff Rates, Tariff Revenue, and Tariff Reform: Some New Facts

This article compares the statutory ad valorem tariff rates(official rates) with the ratio of tariff revenues to importvalues (collected rates) for Jamaica, Kenya, and Pakistan. Itidentifies four general features of the tariff codes, considerswhether these features apply to all developing countries, anddiscusses four implications of these features for tariff reform.First, the collected rate for any given item in the tariff codeis only weakly related to the official rate for that item. Second,the variation of collected rates around the official rate increaseswith the level of the official rate. Third, the collected rates,on average, increase much less than the official rates. Fourth,the relation between official rates and collected rates is nonlinear,because the slope is lower at higher levels of the officialrate.     

Measuring the hedonic and utilitarian sources of consumer attitudes

It has been suggested theoretically that consumer attitudes have distinct hedonic and utilitarian components, and that product categories differ in the extent to which their overall attitudes are derived from these two components. This paper reports three studies that validate measurement scales for these constructs and, using them, show that these two attitude dimensions do seem to exist; are based on different types of product attributes; and are differentially salient across different consumer products and behaviors, in theoretically-consistent ways.     

Technical Progress and Real Wages Once again

We construct a general equilibrium model of trade and show that an economy can experience technological progress and declining real wages provided that it is open to trade and import demand is sufficiently inelastic in both countries. This is a puzzling outcome so far as marginal productivity paradigm is concerned. In this context we demonstrate that new technology works differently in a closed vs an open economy. In an open economy, technical improvements may generate a fall in labor real earnings, but not in a closed economy. In addition, technical progress in manufacturing must increase manufacturing–service wage gap according to marginal productivity doctrine. We show that the opposite outcome can occur theoretically in an open economy—yet another seemingly puzzling labor market outcome.     

The US Trade Deficit and the Rate of Interest

It is well known that nations with high trade deficits normally have higher interest rates than those with surplus or balanced trade. However, such has not been the case with the USA, which has seen a relentless trade deficit since 1982. Its interest rates have been lower than those prevailing in many trade‐surplus nations. Furthermore, these rates fell even as the trade shortfall shot up, generating an interest‐rate paradox. This paper demonstrates that, unlike for other nations, the rising trade deficit itself became the cause of lower US interest rates, and this happened because of the world's strong interest in maintaining a high value of the dollar.
