The article studies stochastic optimization of an intertemporal consumption model to allocate financial assets between risky and risk-free assets. We use a stochastic optimization technique, in which utility is maximized subject to a self-financing portfolio constraint. The papers in literature have estimated the errors of Euler equations using data from financial markets. It has been shown that it is sufficient to test the first order Euler equation implied by the model. However, they all assume a constant consumption–wealth ratio that constrains the boundary conditions, hence influencing the coefficient of the risk premium. The main contribution of our article is that we drop the assumption of a constant consumption–wealth ratio. We have an analytical solution using a utility maximization model with a stochastic self-financing portfolio. We introduce a terminal condition of wealth with and without bequests. We also simulate the stochastic optimization with a self-financing portfolio, distinguishing risk neutral investors (γ-low) from high risk averse investors (γ-high). We show that the model with bequest has a higher level of wealth and a smoother decline of consumption over time than the model with no bequest at the end of the period. The model with no bequest has the same level of consumption and a sharp fall at the end of the period. Risk averse agents with high return assets have a higher amount of wealth than risk-neutral agents with lower return assets. 相似文献

Standard redistributive arguments suggest that the impact of household income on preferences for public education spending should be negative, because wealthier families are likely to oppose the redistributive effect of public funding. However, the empirical evidence does not confirm this prediction. This paper addresses this ‘puzzle’ by focusing on the role of the inclusiveness of the education system and the allocation of public spending between tiers of education in shaping the impact of income on preferences. By using data from the International Social Survey Programme (2006), we show that, when access to higher levels of education is restricted (low inclusiveness) and when the share of public spending on tertiary education is high, the poor are less likely to support public education spending. This result suggests that reforming the education system towards greater inclusiveness might contribute to increase political backing for public investment in education from the relatively poor majority of the population. 相似文献

In the Netherlands auditors can be trained in a part-time educational track in which students combine working and studying or in a full-time educational track. The former training is relatively firm-specific whereas the latter training is relatively general. Applying human capital theory, we expect higher wage growth for full-time educated auditors than for dual-educated auditors. Furthermore, full-time educated auditors may have better outside options than part-time educated auditors. This may make it easier for them to switch employers than for the part-time educated auditors. The predictions on tenure and wages of differently educated auditors are supported by the estimation results in this paper. The part-time, dual track appears an important route for students from a lower socioeconomic background. 相似文献

Studies on structural education choice models are often inconsistent in choosing whether and how to include a disutility of education, especially in an environment with risk and wealth inequality. We show that adding a disutility term to the education decision, a human capital investment option, is equivalent to assuming a relationship between wealth, risk, and education. Utility gain from education is increasing in the riskiness of future consumption. A riskier environment further propels an agent to choose the human capital investment option that maximizes future income. If the degree of risk increases heterogeneously across multiple human capital investment options, risk aversion and the precautionary savings motive can compound or negate each other depending on which option has a greater increase in risk. 相似文献

Herding among analysts emerges when analysts give priority to their peers’ opinions instead of their own beliefs or information. Some circumstances may enhance or restrain this type of behaviour. We postulate that market sentiment is one of them. This article analyses the effect that investor sentiment may have on analysts’ herding behaviour in the U.K. Our results suggest that ‘easy situations’ such as analysing easy-to-value securities and releasing optimistic information at times of high market sentiment clearly reduce herding practices, whereas herding clearly increases in difficult situations when analysts have to release negative information at moments of high investor sentiment. 相似文献

Pairs trading is a dollar-neutral trading strategy. Using the components of two major stock indices, the S&P 500 and the Nikkei 225, this article deals with the performance of a pairs trading system based on various pairs selection methods (distance, stationarity, cointegration) over a 10-year period. On both markets, using a classical framework, cointegration appears superior and effective. On the U.S. market and also in Japan to a lower extent, pairs trading strategies exhibited an impressive performance during the 2008 financial crisis. Bearish periods are associated with a high level of the VIX index: the ‘investor fear gauge’. Using a modified trading system, this article examines the link between pairs trading performance and volatility/VIX timing. It is shown that for the best selection technique (cointegration), timing volatility has no economic value in a pairs trading context. 相似文献

Emotions can affect individuals' preferences and economic behavior. In this paper we consider the relationship between emotions and anchoring effects in non-market valuation. The findings show that although anchoring effects are relevant, elicited preferences are coherent, in the sense that they are sensitive to changes in the dimension of the good. Additionally, it is found that the relationship between emotional intensity and the level of anchoring is U-shaped, with anchoring declining as emotional intensity rises until a minimum is reached. Thus, preferences can be substantially less affected by anchoring effects if emotional intensity deviates from extreme values. Finally, it is found that the degree of sensitivity to scope is influenced by the level of emotional load involve in the valuation task. 相似文献

Since time preferences constitute a concept fundamental to economics, many economists have attempted to elicit time preferences by using multiple price lists. In such endeavours, however, little attention has been paid to the effect of the ordering of questions on elicited time preferences although the ordering effect is well known. We analysed a representative sample of the Indonesian population (13,870 men and 15,858 women) by applying censored maximum likelihood regressions. We exploited the randomized ordering of two series of delay questions (1- and 5-year delays) and estimated the causal effect of the ordering on elicited time preferences. Respondents who considered the longer-delay questions exhibited more patience, and the effects were larger for women. Economists need to take into account the ordering effect as they design experiments by which to elicit time and other preferences. 相似文献

Preferences for charitable giving in auctions can be modeled by assuming that bidders receive additional utility proportional to the revenue raised by an auctioneer. The theory of bidding in the presence of such preferences results in a very counterintuitive prediction which is that, in many cases, bidders having preferences for charitable giving does not lead to a substantial revenue advantage for an auctioneer. We test this theory and this prediction with a series of experiments. In one experiment we induce charitable preferences exactly as specified in the model to see if bidders respond to them as predicted. We find that they do. We then conduct a second experiment in which the revenue from the auctions is donated to actual charities to verify the robustness of the prediction when charitable preferences are generated by a more natural source and find again that the theoretical prediction holds: even strong charitable preferences do not result in substantial revenue increases to the auctioneer. 相似文献

We model decision making under ambiguity based on available data. Decision makers express preferences over actions and data sets. We derive an α-max–min representation of preferences, in which beliefs combine objective characteristics of the data (number and frequency of observations) with subjective features of the decision maker (similarity of observations and perceived ambiguity). We identify the subjectively perceived ambiguity and separate it into ambiguity due to a limited number of observations and ambiguity due to data heterogeneity. The special case of no ambiguity provides a behavioral foundation for beliefs as similarity-weighted frequencies as in Billot et al. (2005) [3]. 相似文献

This article examines the empirical link between financial openness and informational efficiency of stock markets in 27 emerging markets. Improving on earlier papers, this study has used World Bank’s Worldwide Governance Indicators (WGI) as the proxy of institutional development in dynamic panel data models estimated by generalized method of moments (GMM). Our results show, first, financial liberalization by itself has no impact on enhancing efficiency of stock market. Second, for countries with high level of institutional development, the interaction of trade openness and financial openness become significant. Third, for the same group of countries, interaction effect of financial liberalization and institutional development leads to more efficiency in stock market. Hence, our finding demonstrates the utmost importance of institutional development and its role on liberalization. Our results conclude that institutional development and trade openness are pre-requisites for a country to benefit from financial openness. Our study further provides empirical evidence to theoretical model proposed by Basu and Morey (2005) that governance is the missing link between stock market efficiency and financial liberalization. Our findings suggest that policy makers in developing economies should enhance the quality of their institution in order to optimize the benefits of financial liberalization. 相似文献

How important is the demographic transition for economic growth? To answer this question, this paper constructs a general equilibrium overlapping generations model with endogenous fertility. The model is calibrated to data from Taiwan, a country that experienced rapid economic growth while undergoing significant demographic transition. Our results suggest that more than one-third of the output growth in Taiwan during the past four decades can be attributed to demographic transition, while TFP growth explains another third and the remainder is mainly due to skill-biased technological progress. Our results show that demographic change is an important driver of the growth process in countries undergoing rapid fertility decline. 相似文献

In mixed oligopolies, technology licensing from a cost‐efficient firm to a cost‐inefficient firm has been widely observed. This paper examines the relationship between privatization and licensing (by public or private firms) with the consideration of either a domestic or a foreign private firm. We find that (a) in the case of a domestic private firm, public licensing facilitates privatization, but private licensing hinders privatization; (b) in the case of a foreign private firm, both public and private licensing facilitate privatization. Our results yield important policy implications on privatization. 相似文献

This paper utilises the occupational attainment approach to investigate immigrant labour market assimilation, complementing other assimilation approaches such as employability, earnings, skills-match and job satisfaction. Our results show that all immigrant groups suffer from initial occupational attainment disadvantage. Worryingly, no ‘catch-up’ over time is evident – even when disaggregated to reflect different cultures and backgrounds. Nor is there much evidence that the occupational status of younger arrivals matches those of Australian born residents, despite being immersed in local mores and institutions while undertaking schooling in Australia. Newer cohorts of immigrants (those who arrived between 2000 and 2014) are also more prone to suffering an occupational penalty. We recommend policymakers subsidise bridging courses to aid recognition of overseas-obtained qualifications and encourage immigrants to obtain local qualifications that can complement their overseas-obtained work experience. This will increase their ‘Australian-ready’ skill-set and occupational attainment in their new host country. 相似文献

The objective of this article is to predict, both in sample and out of sample, the consumer price index (CPI) of the US economy based on monthly data covering the period of 1980:1–2013:12, using a variety of linear (random walk (RW), autoregressive (AR) and seasonal autoregressive integrated moving average (SARIMA)) and nonlinear (artificial neural network (ANN) and genetic programming (GP)) univariate models. Our results show that, while the SARIMA model is superior relative to other linear and nonlinear models, as it tends to produce smaller forecast errors; statistically, these forecasting gains are not significant relative to higher-order AR and nonlinear models, though simple benchmarks like the RW and AR(1) models are statistically outperformed. Overall, we show that in terms of forecasting the US CPI, accounting for nonlinearity does not necessarily provide us with any statistical gains. 相似文献

We use a two-country new open economy macroeconomics model describing a currency union with imperfect financial integration. We assume that household preferences are biased towards the goods produced within the country. We use this setup to show how the degree of financial integration and the home bias affect the welfare efficiency of fiscal policy. This is particularly important for the implications of a fiscal policy launched by a member of the euro zone where the home bias is in a decreasing trend due to higher goods market integration and where there are explicit efforts to enhance financial integration. The results show in particular how the effects of an increasing financial integration on the impact of a fiscal policy can be mitigated or amplified by a decreasing home-product bias. Moreover, under certain conditions, the degree of financial integration has no effect on the welfare efficiency of fiscal policy despite its non-negligible effects on the components of welfare. 相似文献

There is a large literature that finds that common law countries perform better than civil law countries in various aspects of the institutional environment. This article extends these findings to another dimension of institutional quality??the cost of registering property. In a sample of 121 countries, we find that the cost of registering property is lower by 26 percent of the world average in common law compared with civil law countries, a result largely driven by differences in non-notary costs of registering property. We provide plausible explanations for these findings. 相似文献

This paper investigates whether financial intermediary development influences macroeconomic technical efficiency on a sample of 47 countries, both developed and developing, over 1980–1995. We do so by applying Battese and Coelli (1995)'s method at the aggregate level. It is found that financial intermediary development, except financial depth, is on average associated with more efficiency. However we find strong evidence that this relationship is conditional on the level of economic development. The lower the economic development the weaker is the impact of financial development on efficiency. That impact can even become negative in the poorest countries. 相似文献

This study examines the impact of environmental regulations stringency on agricultural trade between European Union (EU) and Middle East and North Africa (MENA countries). Using a gravity model and applying the zero-inflated Poisson (ZIP) model, we estimate the impact of environmental regulations stringency on bilateral agricultural exports between 28 EU and 20 MENA countries during the period 2001–2014. The results have showed that environmental regulations do matter for agricultural trade between both regions because in the presence of excessive zero trade observations, they act as significant fixed export costs that affect the probability of trade. More stringent environmental regulations stimulate innovative efforts in cost-saving green technologies, which increase productivity and positively affect agricultural exports. The results have favoured the revisionist Porter hypothesis (PH), according to which environmental regulations may stimulate innovative efforts, which mitigate the negative effects of higher fixed abatement costs and enhance trade competitiveness. 相似文献
