This paper develops a real options model of an all-equity financed firm that receives mean-reverting earnings and is subject to progressive taxation. Tax progression arises from an exogenously given tax exemption threshold such that the firm pays no corporate income taxes should its earnings be less than this threshold. The firm possesses a perpetual option to liquidate its operation for a deterministic salvage value at any time. We show that the firm optimally exercises the liquidation option at the first instant when its earnings reach an endogenously determined threshold (the liquidation trigger) from above. Using numerical analysis, we show that the liquidation trigger is higher or lower than the exogenously given tax exemption threshold, depending on whether the tax exemption is below or above a unique critical level, respectively. We further show that the liquidation trigger is strictly decreasing for all tax exemption thresholds less than the critical level, and can be hump-shaped for all tax exemption thresholds greater than the critical level, especially when the salvage value is small. Corporate income taxes as such are not neutral when tax schedules are progressive. 相似文献

This paper considers the consequences of a large scale mortality shock arising from a famine or epidemic for long run economic and demographic development. The Great Irish Famine of 1845–1852 is taken as a case-study and is incorporated as an exogenous mortality shock into the type of long-run unified growth theory pioneered by Galor and Weil (1999, 2000), and modelled by Lagerlöf (2003a,b) among others. Through calibration, the impact of such a mortality shock occurring on the cusp of a country's transition from a Malthusian to a Modern Growth regime is then depicted. 相似文献

On the welfare benefits of an international currency 总被引:2,自引:0,他引:2

Is it beneficial for a country's currency to be used internationally? And, if so, can we quantify the benefit? Since the emergence of the euro, there has been great interest in the consequences of a transfer of the dollar's premier international role to the euro. This paper presents a novel model-based approach towards assessing the welfare benefits associated with the international use of a country's currency. Apart from the familiar benefits associated with seigniorage, residents of the issuing country experience an increase in the purchasing power of their currency both at home and abroad. In the calibration exercise carried out in this paper, we find the benefits of an international currency to be quantitatively significant. The welfare gain for the Euro area in having the euro internationally used ranges from 1.9% to 2.3% of consumption depending on relative inflation rates. The rest of the world is not indifferent as to which currency circulates as the dominant international currency. Conditional on their currency not being used internationally, their preference is for the dominant international currency to be the one with the lowest inflation rate. 相似文献

This paper presents a model-based analysis of the development and diffusion of so-called ‘green’ products, i.e. those which are easily recyclable and which have a long lifetime. We address this problem by developing an evolutionary simulation model to identify the impact of the environmental R&D strategies of business firms on the economy and the environment. The simulation results show that R&D investment both in product recyclability and in product lifetime extension can be positive for the firm. Adopting such a strategy means that the firm can then market green products, which provides it with a competitive advantage on firms investing mainly in product recyclability whatever consumers' preferences. From an environmental point of view, the diffusion of green products will reduce both waste flows in the economy and pressure on virgin resources. However, diversifying R&D investment to develop both product recyclability and lifetime can mean slowing down the flow of recycled materials and may lead to even greater quantities of unrecycled waste. Our results suggest introducing regulation policies aiming at encouraging firms to invest both in product recyclability and lifetime in order to benefit from their complementarities. Furthermore, simulations show that it should be better to direct environmental policies on firms' environmental innovation strategies than on demand attributes because significant changes in these strategies would provide much more radical environmental changes. 相似文献

This paper employs recently developed non-stationary panel methodologies that assume cross-section dependence to estimate a production function for Italian regions over the 1970–2003 period. The analysis consists of three steps. First, unit root tests for cross-sectionally dependent panels are applied. Second, the existence of a cointegrating relationship among value added, physical capital and human capital-augmented labour is investigated, fully allowing for cross-section dependence. Then, the appropriate Fully Modified Ordinary Least Square estimators developed by Bai and Kao [Bai, J., Kao, C. 2006. On the Estimation and Inference of a Panel Cointegration Model with Cross-Sectional Dependence. In: B.H. Baltagi (Ed) Panel Data Econometrics: Theoretical Contributions and Empirical Applications, Elsevier Science: Amsterdam; 2006, pp.3–30.] are used to estimate the long-run relationship. We find that neglecting cross-section dependence can have a strong impact on the estimated long-run input elasticities, generally imparting them an upward bias. 相似文献

Does production risk suppress the demand for credit? We implemented a randomized field experiment to ask whether provision of insurance against a major source of production risk induces farmers to take out loans to adopt a new crop technology. The study sample was composed of roughly 800 maize and groundnut farmers in Malawi, where by far the dominant source of production risk is the level of rainfall. We randomly selected half of the farmers to be offered credit to purchase high-yielding hybrid maize and groundnut seeds for planting in the November 2006 crop season. The other half of farmers were offered a similar credit package, but were also required to purchase (at actuarially fair rates) a weather insurance policy that partially or fully forgave the loan in the event of poor rainfall. Surprisingly, take-up was lower by 13 percentage points among farmers offered insurance with the loan. Take-up was 33.0% for farmers who were offered the uninsured loan. There is suggestive evidence that reduced take-up of the insured loan was due to farmers already having implicit insurance from the limited liability clause in the loan contract: insured loan take-up was positively correlated with farmer education, income, and wealth, which may proxy for the individual's default costs. By contrast, take-up of the uninsured loan was uncorrelated with these farmer characteristics. 相似文献

This article deals with both theoretical and empirical analyses of the post‐war (1960–2004) growth for the USA and Japan. We investigated three factors contributing to growth: the growth rates of capital, labour and labour saving innovation. In Japan, the growth rate of the labour force has been much less important than its quality improvement—i.e. labour saving technical change—while in the USA, the growth rates of labour and population have contributed more than their quality improvement. The policy implication is that Japan's declining population can be compensated for by additional quality improvement of the existing labour force. 相似文献

The point of departure of Piketty's influential Capital in the Twenty‐First Century (2014) was the dramatic growth of private wealth‐income ratios in advanced economies between 1970 and 2010. Using official balance sheet data for South Africa—the first country to publish such data in the developing world—, this paper examines to what extent this re‐emergence of private wealth was also experienced in the developing‐country context. First, we find that the South African current wealth‐income ratio is very close to its 1975 level, and much lower than those of Piketty's sample of advanced economies. Second, we show that the discrepancy is explained not only by South Africa's relatively low savings rates, but also by the reduction of wealth before and during the transition to democracy in the 1990s. Since then, private wealth recovered significantly, but the U‐shaped relationship does not support the argument that there is a clear correlation between the capital‐income ratio and capital share. 相似文献

Social Impact Bonds (SIBs) have emerged in recent years as outcome‐based public‐private partnerships (PPP) for the delivery of welfare services, where the payment to the private operator is linked to the achievement of superior social impact. Since the traditional infrastructure‐based PPP approach seems to have failed to achieve higher level of efficiency and, above all, effectiveness, this paper discusses the extent to which the SIB model can represent a reference point to innovate the PPP model by introducing more focus on outcome achievement and social value generation. 相似文献

We analyse the legitimacy of public enterprises that perform economic activities by focusing on the citizens’ subjective preferences, i.e. determining their political legitimacy. Using data from a representative survey conducted among 318 citizens of the German state of Rhineland‐Palatine, we explore determinants for the support of either privatisation efforts or the instrumental thesis, a widespread principle in German‐speaking countries, which considers public enterprises solely as instruments to fulfil economic policy objectives. Our results indicate that the respondents’ perception of the efficiency of public enterprises as well as their personal economic situation are important factors for the support of privatisation. The influential factors for the use of public enterprises as policy instruments are political ideology, the perception of a higher security of supplying goods and services as well as opinions regarding corporate social responsibility. The subjective preferences of a (democratic) country's citizens are thus an important reason why the public sector should or should not play an active part in providing goods and services. This can play an important role when decision makers from the public sector are keen to take into account the citizens’ approval or disapproval of privatisation measures. 相似文献
