This paper studies a dynamic portfolio choice problem for an investor with both wealth-dependent risk aversion and wealth-dependent skewness preferences. In a general economic setting, the solution is characterized in terms of a system of extended Hamilton-Jacobi-Bellman (EHJB) equations and the solution is given in closed form in some special cases. We demonstrate the effects of higher order risk preferences and state-dependent risk aversion on the optimal asset allocation decisions. We find that wealth-dependent risk aversion facilitates risk taking and the skewness preference leads to a more positively skewed portfolio in certain circumstances. 相似文献

Accounting and corporate reporting can be seen as a language for specific purposes. Such a language requires the use of terms and concepts with a precise and commonly shared meaning to allow effective and efficient communication. We analyze the term ‘non-financial information’, which has become a part of mandatory corporate reporting within the European Union (EU) through recent regulatory actions. Our analysis is based on a survey of the theoretical and empirical literature, on the rational of semantic theory, as well as on a questionnaire survey. The clear finding is that, up to now, neither a common meaning nor a generally accepted definition of ‘non-financial information’ exists. We derive from the applied theoretical concepts that this situation negatively impacts the efficiency and effectiveness of corporate communication. Against this background we discuss several venues that might help to overcome this deficiency like issuing a mandatory guideline or changing the terminology. 相似文献

The value for money of a standard annuity is the higher, the longer the life expectancy of an insured, and therefore it is only acceptable for persons with an above average life expectancy. The discrepancy is intensified by tax regulations that favor lifelong annuity payments opposed to a lump sum. This discrimination of impaired insureds could be prevented if so-called enhanced annuities were offered, i.e. products where the annuity paid is the larger, the lower the person’s life expectancy. The article presents a quantitative comparison of the risk profile of insurance companies offering standard annuity contracts compared to enhanced annuities and an analysis of the impact of adverse selection on a standard insurer. By definition of individual mortality rates a heterogeneous insurance portfolio is specified. Besides we model the individual underwriting of enhanced annuities. A Monte Carlo Simulation provides results to compare the profit/loss situation of a portfolio of traditional annuity products and a portfolio of enhanced annuities with individual underwriting of different quality and to assess the impact of selection effects. 相似文献

Using order book information from the Australian Stock Exchange (ASX), we examine whether (and to what extent) the order book affects investors' order placement strategies. We find that the top of the book always affects order submissions, cancellations, and amendments, and the rest of the book mostly affects order cancellations and amendments. The previously documented order submission aggressiveness, given a crowded first step of the book, persists to other price steps and is found in order amendments and cancellations along the book. Finally, investors tend to fill in the large price gaps in the book by submitting or amending orders. 相似文献

This paper, considering revenue and cost exposure channels, investigates the effects of exchange rate on fixed capital investment in Mexican manufacturing sector over 1994–2003. We find that i) currency depreciation has a positive (negative) effect on fixed investment through the export (import) channel; ii) exchange rate volatility impacts mostly export oriented sectors; iii) the sensitivity of investment to exchange rate movements is stronger in non-durable goods sectors and industries with low mark-up ratios. 相似文献

Unemployment and the Real Wage Gap: A Reappraisal of the German Experience.- The major European economies experienced a rise in unemployment since the late 1970s. At the same time, the real wage gap, a widely used measure of wage pressure, declined. This paper develops an analytical framework that relates the two phenomena. Particular emphasis is placed on the interaction of capital accumulation, wage setting and labour demand. The model is applied to the particular case of Ger-many and found to be consistent with the observed behaviour of wages, investment, output and employment. 相似文献
