Stable partnerships, matching, and local public goods

In the presence of local public goods differences in tastes are an important determinant of the way in which partnerships are formed. Heterogeneity in tastes for private vs. public goods produces a tendency to positive assortment and partnerships of couples with similar tastes; heterogeneity in tastes for different public goods brings about partnerships of couples with similar tastes only if there is a significant overlap in the distribution of tastes of the two groups to be matched. We show that with two public goods we may get negative assortment, pure positive assortment being only one of many possibilities.     

The Anatomy of a Socially Responsible Corporation

Prior research treats corporate social responsibility (CSR) as a unitary construct. Using principal component analysis, we show that CSR activities can be divided into two types: responsive CSR (RCSR), which includes initiatives that address specific concerns caused by firm activity, and adaptive CSR (ACSR), which are initiatives that anticipate concerns before they arise. We find that responsive motives are roughly three times more dominant than adaptive motives. Larger firms, older firms, and more diversified firms invest more in RCSR while younger firms and more focused firms tend to invest more in ACSR.     

Joint decision of procurement lot-size,supplier selection,and carrier selection

The joint decision making of procurement lot-size, supplier selection, and carrier selection has potential to reduce buyer's purchasing expenditures. Furthermore, the total logistics cost can also come down through economies of scale in the purchasing and transportation costs, and reduction in supply chain disruptions such as rejections and late deliveries. We study a procurement setting in which a buyer needs to purchase a single product from a set of suppliers over finite discrete time periods to satisfy service level requirements. The suppliers offer all-unit quantity discounts, and transportation cost depends on carrier capacity as well as geographical location of suppliers. This paper proposes an integer linear programming model to simultaneously determine the timings of procurement, lot-sizes, suppliers and carriers to be chosen so as to incur the least total cost over the planning horizon. A numerical example is included to demonstrate the effectiveness of the proposed model in establishing tradeoffs among purchasing cost, transaction cost, and inventory holding cost. Sensitivity analysis has been carried out to understand the effects of the model parameters on the purchasing decisions and total cost. Managerial insights of this study serve as a reference for decision makers to develop effective procurement strategies.     

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.     

Are Tariffs Inflationary?

Economists universally regard tariffs to be inflationary and free trade to be deflationary, a view that this paper challenges. It is argued that while rotectionism has generally created inflation in developing economies, the experience of the United States was totally different. Tariffs in the US were never associated with rising prices, and trade liberalization with declining prices. High tariffs were always followed by sharp drops in the cost of living. A theoretical model is developed to explain the deflationary effects of tariffs in the United States. Thus tariffs produce inflation only in nonmarket or ualistic developing economies, but not in advanced economies.     

A theory of employment guarantees: Contestability,credibility and distributional concerns

Both raw intuition and past experience suggest that the success of an employment guarantee scheme (EGS) in safeguarding the welfare of the poor depends both on the wage it promises, and the ease with which any worker can gain access. An EGS is thus at once a wage guarantee and a rationing device. We chart the positive and normative limits of such an EGS as an efficiency improving and poverty alleviating policy reform in a canonical labor market setting. At its core, an EGS provides an aggregate, not just EGS, employment target. Given the target, the EGS wage and access can be fine-tuned to deliver outcomes ranging from a contestable labor market to a simple universal unemployment benefit. The credibility of any such target, however, is shown to be triggered endogenously by a host of factors: the distributional concerns of the planner, private sector productivity, the prevalence of market power and the need for public works. Paradoxically, the outcome with a planner who cares only about efficiency can be less efficient than the outcome with a planner whose social welfare function also gives weight to poverty!     

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.
