This paper presents a two-sector model of an economy – one sector consisting of large firms with institutionally determined wage (the Formal sector) and the other sector consisting of small firms (the Informal sector). The paper examines the effects of changes in benefits, entrepreneurial zeal, and the institutionally determined wage in the Formal sector on unemployment. It concludes with brief comments on the role of aggregate demand and supply policies in reducing unemployment in this economy. 相似文献

We obtain a sufficient condition forE-optimality of equireplicate designs. As an application, we proveE-optimality of certain types of three-class PBIBDs based on rectangular association scheme — in short — rectangular designs. These designs turn out to be highly efficient with respect to theA-criterion as well. We also observe that these designs, though themeselves not regular graph designs (RGD's) are yet strictlyE-better than every competing RGD, wheneverv≥26 andv=2 (mod 4). This provides an infinite series of counter examples to the conjecture of John and Mitchell (1977). We also present two methods of construction of the rectangular designs. Apart from providing infinitely many examples of the designs provedE-optimal in this paper and in Cheng and Constantine (1986), this construction also provides — as a special case — the first known infinite series of most balanced group divisible designs, which were proved optimal with respect to all type 1 criteria by Cheng (1978). 相似文献

This paper addresses - with the help of numerical simulations - some of the issues relating to income distribution in the context of development of an economy with an informal sector and migration of both low- and high-skilled workers from the rural to the urban area. A major aim has been to see under what conditions we do or do not get an inverted U-shaped curve of income distribution. The paper finds that the tendency always is for the Gini coefficient to rise and then decline. However, once it starts declining, it need not continuously decline; it may rise, then decline, then rise again and indeed rise above the previous peak before starting to decline again and may well end at the end of the simulation at a higher value than at the start. Any case for the redistribution of income is seen to be much stronger at the later stages of development that at earlier stages, even though at later stages, Gini coefficient may be lower than at earlier stages. The policy implications of the findings are considered. 相似文献

In donation contexts, many advertising appeals focus on the benefits that those in need will receive as the result of donations. Yet little is known about the effect that benefit information has on willingness to give. In this research, we differentiate between two types of benefits typically emphasized in appeals: emotional (which focus on the positive emotions beneficiaries experience as the result of donations) and functional (which focus on the basic needs met as the result of donations). We conduct three experiments and find that appeals focusing on emotional benefits increase willingness to donate relative to appeals that focus on functional benefits. We also provide evidence that visualization of benefits mediates the effect of benefit type on willingness to donate and introduce relevant moderators. In addition to contributing to theoretical understanding of donation behavior, this research also provides managers with practical tools to encourage donations. 相似文献

STOCHASTIC HYPERBOLIC DYNAMICS FOR INFINITE-DIMENSIONAL FORWARD RATES AND OPTION PRICING 总被引:1,自引:0,他引:1
We model the term-structure modeling of interest rates by considering the forward rate as the solution of a stochastic hyperbolic partial differential equation. First, we study the arbitrage-free model of the term structure and explore the completeness of the market. We then derive results for the pricing of general contingent claims. Finally we obtain an explicit formula for a forward rate cap in the Gaussian framework from the general results. 相似文献

The standard neoclassical life-cycle model predicts that individual consumption should either increase, remain constant or fall monotonically depending on whether the market rate of return on savings is greater than, equal to or less than the discount rate. However, empirical evidence suggests that even after controlling for economic growth and family size, household consumption exhibits a robust hump at around age 45–55, with the ratio of peak consumption to consumption when entering the workforce greater than 1.1. This paper extends the “overconfidence” explanation (Caliendo and Huang, J. Macroecon 30(4):1347–1369, 2008) of this macroeconomic puzzle to a calibrated general equilibrium environment. The main finding is that although it is possible to identify parameter values under which overconfidence alone generates life-cycle consumption profiles and macro-indicators consistent with U.S. experience, quite extreme assumptions about both the magnitude and distribution of overconfidence in the population are generally required to obtain them. 相似文献

Numerous studies document a day-of-the-week effect in stock returns. Although a common explanation for this phenomenon concerns a potential daily pattern in the release of corporate information, existing studies provide conflicting evidence. To aid in resolving this issue, possible seasonalities in a sample of 138,824 dividend announcements are investigated over twenty-six years across 3,484 firms. Tests provide no support for the information hypothesis and suggest that the anomalous pattern of returns is driven by some factor unrelated to information arrivals. 相似文献
