We analyze the impact of a drop in fertility on the optimal allocation of resources in an overlapping generations economy where old workers care about leisure. We also characterize optimal dynamics and study the decentralization of the optimum by means of inter‐generational transfers and/or public debt. We conclude that the policy recommendations of postponing retirement is fragile and depend on preferences and technologies. Also, even when the optimal adjustment of public debt goes into the expected direction in the long run—i.e., public debt should decrease—this may not be the case during the transition. 相似文献

Abstract. We present a non-scale continuous-time overlapping-generations growth model that provides an explanation for why economies with relative wage rigidity feature higher unemployment, but not slower productivity growth, than economies with flexible wages. The compression of the wage distribution associated with relative wage rigidity slows down human capital accumulation and growth ceteris paribus . But unemployment among the low-skilled workers strengthens the incentives to invest in human capital and, hence, growth. The two effects are offsetting, and growth is independent of the prevailing degree of relative wage rigidity. This knife-edge result is robust with respect to some modifications of the model. 相似文献

A bstract . In the last decades, revolutionary changes in financial markets, instruments, and institutions have stimulated empirical and theoretical investigations into the interaction of the financial and the "real" side of economic systems. While a considerable body of empirical investigations seems to provide evidence of positive correlations between stock market development and economic growth, there is no consensus in other social sciences as to whether there are two-way linkages, and if so, how to conceive a possible mechanism of interaction. Particularly, the hypergrowth and ubiquity of financial markets has triggered controversial debates on how to understand today's economic landscape. With the objective of clarifying the relationship between finance and economy, this article restructures the present debate through the lenses of Talcott Parsons's and Niklas Luhmann's theories of social systems. Basic system-theoretical ideas on social aspects of finance and economy as well as on uncertainty and risk hint at new insights into the global system of finance that might go far beyond explanatory models of causality. 相似文献

Traditional life insurance products, in particular participating life insurance contracts, are often criticized. Their performance is often said to be poor compared to other investment alternatives. Interestingly, this perception appears to persist although very little research has been conducted into the performance of participating life insurance contracts. But are participating life insurance contracts actually bad for policyholders? We conduct a performance analysis based on contracts offered in the German market, in order to provide evidence to support decision making by policyholders. 相似文献

Can pure play internet banking survive the credit crisis? 总被引:1,自引:0,他引:1
This paper positions the pure-play internet banking model (PPI) as a hybrid business model that combines features of both relationship and transaction banking. Although in terms of customer orientation PPI banks may partly resemble relationship banks, they lack their comparative advantage in generating borrower-specific information. Instead, the characteristic features of PPI banks are low costs and easy scalability. While the latter may enable PPI banks to quickly capture market share, it may also generate overexposure in risky markets. We present a case study on ING Direct, one of the leading global PPI banks and address the sustainability of the PPI business model by comparing the ING Direct foreign operations. The findings for ING Direct are validated using data for E-Trade Bank. We conclude that managing growth appears to be the prime challenge to PPI banks. 相似文献

Accounting for asset write‐downs has received substantial media attention throughout the Global Financial Crisis and has been the subject of academic debate and numerous accounting regulations during the past three decades. This study provides evidence of the magnitude and frequency of quarterly asset write‐down activities for a sample of US firms between 2001 and 2008 and examines whether reported asset write‐downs mirror market and economic indicators during the sample period. 相似文献

The role of strategic enterprise risk management and organizational flexibility in easing new regulatory compliance 总被引:1,自引:0,他引:1

The impact of new regulatory requirements for internal control reporting on an organization's ability to maintain strategic flexibility has been debated in the popular press extensively. This paper tests theory from strategic management to examine the relationship between an organizations' pre-regulatory strength of strategic enterprise risk management (ERM) processes and their ability to react to new regulatory mandates. In the context of companies' adoption of SOX Section 404 internal control reporting requirements, we examine organizations' pre-SOX ERM processes, ERM supporting technologies, and organizational flexibility in order to better understand the antecedents to the difficulty encountered in meeting SOX 404 requirements. Using responses from 113 Chief Audit Executives (CAEs), we find that organizations with stronger strategic ERM processes and flexible organizational structures already in place incurred little difficulty in implementing SOX 404 mandates. On the other hand, organizations using weaker ERM processes, which focused on control compliance, experienced more difficulty. These findings provide key insights into the importance of strategic ERM in effectively complying with new regulatory controls in volatile environments. 相似文献

Supply network capacity planning for semiconductor manufacturing with uncertain demand and correlation in demand considerations 总被引:2,自引:0,他引:2

A semiconductor supply network involves many expensive steps, which have to be executed to serve global markets. The complexity of global capacity planning combined with the large capital expenditures to increase factory capacity makes it important to incorporate optimization methodologies for cost reduction and long-term planning. The typical view of a semiconductor supply network consists of layers for wafer fab, sort, assembly, test and demand centers. We present a two-stage stochastic integer-programming formulation to model a semiconductor supply network. The model makes strategic capacity decisions, (i.e., build factories or outsource) while accounting for the uncertainties in demand for multiple products. We use the model not only to analyze how variability in demand affects the make/buy decisions but also to investigate how the correlation between demands of different products affects these strategic decisions. Finally, we demonstrate the value of incorporating demand uncertainty into a decision-making scheme. 相似文献
