Dualism is a pervasive feature of the manufacturing sectors of less-developed countries, with large differences in productivity between the informal and the formal sectors. Policy distortions are viewed as an important factor behind the prevalence of manufacturing dualism. We examine whether tariff reforms, industrial de-licensing and the withdrawal of reservation of products for small firms implemented since the mid-1980s have had any effects on efficiency differentials between informal and formal firms in Indian manufacturing. We find strong evidence that economic reforms have exacerbated dualism by increasing the productivity differentials between the more efficient formal firms and the less efficient informal firms. 相似文献

Building on the work of Das and Sundaram (2007), we develop a widely applicable model to price securities subject to interest rate, equity, and default risks and use it to price exchangeable bonds. The extension features a trivariate recombining lattice instead of the original model’s bivariate recombining lattice. We also show how to estimate some critical non-observable inputs to implement the model by using current market data so that the model’s prices reflect current market information. We test the model on a sample of exchangeable bonds to determine the model’s empirical performance. Besides exchangeable bonds, we can also use the model to price securities such as reverse exchangeable bonds, bonds exchangeable to indexes, and bonds exchangeable to commodities. 相似文献

We offer a new paradigm to understand the effects of trade on factor rewards. It utilizes the classical‐Keynesian model, and shows that normally a country’s trade deficit hurts labor by lowering the real wage, but benefits the owners of capital. The effects of tariffs on factor rewards and employment are opposite to those of the trade deficit, which falls with a rise in the tariff rate. Countries with trade shortfalls unambiguously benefit from their tariffs, because laborers far outnumber capitalists, who suffer from the declining interest rate. Thus, tariffs lead to a rise in social welfare in trade‐deficit countries. 相似文献

In this paper we show that measures of economic uncertainty (conditional volatility of consumption) predict and are predicted by valuation ratios at long horizons. Further we document that asset valuations drop as economic uncertainty rises—that is, financial markets dislike economic uncertainty. Moreover, future earnings growth rates are sharply predicted by current price-earnings ratios. It seems that much of the variation in asset prices can be attributed to fluctuations in economic uncertainty and expected cash-flow growth. This empirical evidence is consistent with the implications of existing parametric general equilibrium models. Hence, the channels of fluctuating economic uncertainty and expected growth seem important for interpreting asset markets. 相似文献

Agility is the fundamental characteristic of a supply chain needed for survival in turbulent and volatile markets, which are becoming norms as product life cycles shorten and environmental forces create additional uncertainty resulting in higher risk in the supply chain management. Agility further helps in providing the right product, at the right time to the consumer, which is the main objective of any supply chain. In the present paper, using interpretive structural modeling, interrelationships of the variables, influencing supply chain agility, have been derived. These variables have been categorized according to their driving power and dependence. This methodology provides a means by which order can be imposed on the complexity of such variables. The insight from model would help supply chain managers in strategic planning for improving supply chain agility. 相似文献

Human resource practitioners and academics have increasingly realized the importance of corporate governance for firm human resource activities. This study investigates how one important form of corporate governance, namely, ownership within large, publicly traded firms, is associated with a firm's use of commitment human resource practices (CHRPs), specifically, the use of incentive compensation, profit sharing, and participative decision making. Our findings indicate that the types of large investor, namely, family and institutional, are differentially associated with the likelihood of the firm using these CHRPs. Specifically, family owners with their long‐term investment horizon, as well as their stakeholder orientation, increase the likelihood of the firm using these practices. In contrast, large institutional owners with their shorter‐term investment horizon, as well as their investor orientation, decrease the likelihood of the firm using these practices. Furthermore, among institutional investors, transient institutional investors are negatively associated with these practices, while dedicated institutional investors are not associated with these practices. Taken together, our results regarding the positive association of family ownership and this subset of CHRPs and the negative association of transient institutional investors and this set of practices, have important implications for human resource professionals who not only need to understand how ownership affects HR practices but also how to articulate the value of these investments in order to attract investors. © 2015 Wiley Periodicals, Inc. 相似文献

Objective:To assess the cost-effectiveness of delayed-release dimethyl fumarate (DMF, also known as gastro-resistant DMF), an effective therapy for relapsing forms of multiple sclerosis (MS), compared with glatiramer acetate and fingolimod, commonly used treatments in the US.Methods:A Markov model was developed comparing delayed-release DMF to glatiramer acetate and fingolimod using a US payer perspective and 20-year time horizon. A cohort of patients, mean age 38 years, with relapsing-remitting MS and Kurtzke Expanded Disability Status Scale (EDSS) scores between 0–6 entered the model. Efficacy and safety were estimated by mixed-treatment comparison of data from the DEFINE and CONFIRM trials and clinical trials of other disease-modifying therapies. Data from published studies were used to derive resource use, cost, and utility inputs. Key outcomes included costs, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios. Alternative scenarios tested in a sensitivity analysis included drug efficacy, EDSS-related or relapse-related costs, alternative perspectives, drug acquisition costs, and utility.Results:Base-case results with a 20-year time horizon indicated that delayed-release DMF increased QALYs +0.450 or +0.359 compared with glatiramer acetate or fingolimod, respectively. Reductions in 20-year costs with delayed-release DMF were ?$70,644 compared with once-daily glatiramer acetate and ?$32,958 compared with fingolimod. In an analysis comparing delayed-release DMF to three-times-weekly glatiramer acetate and assuming similar efficacy and safety to the once-daily formulation, 20-year costs with delayed-release DMF were increased by $15,806 and cost per QALY gained was $35,142. The differences in costs were most sensitive to acquisition cost and inclusion of informal care costs and productivity losses. The differences in QALYs were most sensitive to the impact of delayed-release DMF on disease progression and the EDSS utility weights.Conclusion:Delayed-release DMF is likely to increase QALYs for patients with relapsing forms of MS and be cost-effective compared with fingolimod and glatiramer acetate. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献
