We study optimal income and commodity tax policy with credit‐constrained low‐income households. Workers receive an even flow of income during the tax year, but report their incomes and make tax payments (receive transfers) at the end of the year. They spend their disposable income on multiple commodities over the year. We show that differentiated subsidies on commodities can be optimal even if the Atkinson–Stiglitz Theorem conditions apply. When the optimal policy leaves low‐income households with binding credit constraints, it may be optimal to subsidize differentially the good that they consume in higher proportion. Uniform subsidies would also relax the credit constraint, but would be more costly to the government since they would equally benefit unconstrained households. Numerical examples suggest that commodity tax differentiation increases with basic needs and with the interest rate at which government borrows.  相似文献

In this article, we propose several pathwise and finite difference-based methods for calculating sensitivities of Bermudan options using regression methods and Monte Carlo simulation. These methods rely on conditional probabilistic representations that allow, in combination with a regression approach, for efficient simultaneous computation of sensitivities at many initial positions. Assuming that the price of a Bermudan option can be evaluated sufficiently accurate, we develop a method for constructing deltas based on least squares. We finally propose a testing procedure for assessing the performance of the developed methods and give a numerical illustration.  相似文献

Structural changes, i.e. long-run changes in the agriculture-manufacturing-services-structure, are a key property of growth and development processes with massive impacts on economy and society and are part of actual debates regarding policy in developing and developed economies. While traditional literature has attempted to explain structural changes by using autarkic models, recent literature has emphasised the importance of deriving theories of structural change using open economy settings. We elaborate on the impacts of intermediate trade on sector structure. In particular, we study how import of intermediate products, which is increasingly feasible due to improvements in transport technology and political integration, affects sector structure in a multi-sector growth model with capital accumulation. This topic has not been studied in the previous literature on structural change in open economies, despite the fact that intermediate imports and capital accumulation are central aspects of modern developing and developed economies. We show that the impacts of intermediate trade on sector structure depend on three factors: productivity gains from trade, specialisation in international trade and development stage. Depending on the constellation of these factors, intermediate trade may accelerate, decelerate or have no effect on structural change. Thus, the effects of intermediate trade may vary strongly across countries.  相似文献

ABSTRACT

More and more customers attempt to claim what they can, rather than what they are offered by the service firm after service failures. The present article empirically investigates the role of situational characteristics in triggering the intention to overclaim through a mediating process of customer's cognitive and emotional responses to the service failure. The model goes beyond predicting the likelihood of overclaiming behavior and offers some insights related to the magnitude or the extent of such claims. The results indicate that cognitive and affective drivers of overclaiming behavior have different impacts on the magnitude or the extent of such claims.  相似文献

Abstract

As the centenary of the 1917 Russian revolution approaches, it is worth reviewing the past 100 years’ discussion amongst economists on the possibility—or otherwise—of economic planning under socialism. The socialist calculation debate is of fundamental importance, not merely as a specialist application of economic ideas, but as an investigation of the foundations of economic activity. Every economic action is premised upon calculation, every choice depends upon an assessment of the costs and benefits of each alternative between which the agent must choose. The view of that choice and its attendant calculation is constitutive of the schools of thought—Marxian, neoclassical and Austrian—which have contributed to the debate. An understanding of the calculation debate is therefore required to understand how these paradigms stand in relation to each other. This article addresses one aspect of that debate—the claim by Austrian economists that socialism is impossible because the absence of private property in the means of production precludes economic calculation. The article suggests that several control rather than private property is required for economic calculation, and that several control is consistent with public ownership of the means of production. The Austrian argument on this point, therefore, is without force.  相似文献

Besides the more commonly used REITs, German investors can also invest in a lesser-known real estate vehicle, Open-ended Property Funds. OPFs are considered a compromise between listed and direct real estate investments. OPF fund managers generally provide daily (perfect) liquidity. However, if liquidity falls below 5%, share redemptions in these funds can be temporarily suspended for a period of up to two years. During this time, investors will only be able to sell shares on the secondary market (exchange), and are thus subject to significant liquidity risk. The objective of this paper is to analyze whether OPFs add value to investor portfolios above that provided by REITs. We show that OPFs have a diversification advantage over REITs in low-risk portfolios, despite their larger potential liquidity risk. REIT liquidity is comparable to that of ordinary common stock, but OPFs exhibit an average initial discount to funds’ NAV of about 6% when share redemptions are temporarily suspended. However, in the long-run, this potential redemption suspension does not negatively influence OPF performance (in case OPFs reopen again). This makes OPFs an attractive investment alternative to REITs for investors who have a high level of risk aversion and a long-term investment horizon, such as endowments, insurance companies, and pension funds.  相似文献

In this article we propose a novel approach to reduce the computational complexity of the dual method for pricing American options. We consider a sequence of martingales that converges to a given target martingale and decompose the original dual representation into a sum of representations that correspond to different levels of approximation to the target martingale. By next replacing in each representation true conditional expectations with their Monte Carlo estimates, we arrive at what one may call a multilevel dual Monte Carlo algorithm. The analysis of this algorithm reveals that the computational complexity of getting the corresponding target upper bound, due to the target martingale, can be significantly reduced. In particular, it turns out that using our new approach, we may construct a multilevel version of the well-known nested Monte Carlo algorithm of Andersen and Broadie (Manag. Sci. 50:1222–1234, 2004) that is, regarding complexity, virtually equivalent to a non-nested algorithm. The performance of this multilevel algorithm is illustrated by a numerical example.  相似文献
