Abstract. Researchers have used stylized facts on asset prices and trading volume in stock markets (in particular, the mean reversion
of asset returns and the correlations between trading volume, price changes and price levels) to support theories where agents
are not rational expected utility maximizers. This paper shows that this empirical evidence is in fact consistent with a standard
infinite horizon – perfect information – expected utility economy where some agents face leverage constraints similar to those
found in todays financial markets. In addition, and in sharp contrast to the theories above, we explain some qualitative differences
that are observed in the price-volume relation on stock and on futures markets.
We consider a continuous-time economy where agents maximize the integral of their discounted utility from consumption under
both budget and leverage constraints. Building on the work by Vila and Zariphopoulou (1997), we find a closed form solution,
up to a negative constant, for the equilibrium prices and demands in the region of the state space where the constraint is
non-binding. We show that, at the equilibrium, stock holdings volatility as well as its ratio to stock price volatility are
increasing functions of the stock price and interpret this finding in terms of the price-volume relation.

Foreign direct investment, competition and industrial development in the host country 总被引:8,自引:0,他引:8
This paper analyses the impact of foreign direct investment (FDI) on the development of local firms. We focus on two likely effects of FDI: A competition effect which deters entry of domestic firms and positive market externalities which foster the development of local industry. Using a simple theoretical model to illustrate how these forces work we show that the number of domestic firms follows a u-shaped curve, where the competition effect first dominates but is gradually outweighed by positive externalities. Evidence for Ireland tends to support this result. Specifically, applying semi-parametric regression techniques on plant level panel data for the manufacturing sector we find that while the competition effect may have initially deterred local firms’ entry, this initial effect has been outpaced by positive externalities making the overall impact of FDI largely positive for the domestic industry. 相似文献

Top dominance and the possibility of strategy-proof stable solutions to matching problems 总被引:1,自引:0,他引:1
Summary This paper explores the possibility of designing strategy-proof mechanisms yielding satisfactory solutions to the marriage and to the college admissions problem. Our first result is negative. We prove that no strategy-proof mechanism can always choose marriages that are individually rational and Pareto efficient. This strengthens a result by Roth (1982) showing that strategy-proof mechanisms cannot always select stable marriages. The result also applies, a fortiori, to college admissions. Since finding difficulties with strategy-proofness is quite an expected result, we then address a second question which is classical within the incentives literature. Are there restrictions on the preferences of agents under which strategy-proof and stable mechanisms do exist? We identify a nontrivial restriction on the domain of preferences, to be called top dominance, under which there exist strategy-proof and stable mechanisms for both types of matching problems. The mechanisms turn out to be exactly those that derive from the most classical algorithms in the literature; namely, the women's optimal, the men's optimal and the student's optimal. Finally, top dominance is shown to be essentially necessary, as well as sufficient, for the existence of strategy-proof stable matching mechanisms.This work is partially supported by grant PB 89-0294, from the Directión General de Investigatión Ciencia y Tecnología of the Spanish Ministerio de Educación y Ciencia.

The purpose of this paper is tostudy how the choice of environmental standardsby governments is affected by the existence ofwage incomes when firms locations areendogenous. In developed countries labor isunionized, which allows positive wage incomesto arise. Thus, each government has incentivesto persuade firms to locate in its countrysince social welfare depends on suchincomes. But, as pollution damages theenvironment, each government will only try toattract polluting firms to thecountry, to obtain the wage incomes, whenthe valuation of environmental damage showsthat it is low. 相似文献

This paper investigates PTM behaviour in European car markets for a period of great interest (1993-98), taking into account the role of invoicing currency. The results indicate that local currency price stability is a strong and pervasive phenomenon across products independently of the invoicing currency. The paper offers robustness checks, tests and arguments that justify the interpretation of this finding, at least in part, as evidence of PTM. It implies the existence of market segmentation and price discrimination, despite the completion of the single market programme on 1 January 1993. 相似文献

The notional defined contribution model combines pay-as-you-go financing and a defined contribution pension formula. This paper aims to demonstrate the extent to which liquidity and solvency indicators are affected by fluctuations in economic and demographic conditions and to explore the introduction of an automatic balancing mechanism (ABM) into the pension scheme. We demonstrate that the introduction of an ABM reduces the volatility of the buffer fund and that, in most cases, the automatic mechanism that re-establishes solvency produces the highest value of the risk-adjusted notional factor. 相似文献

The improvement of data statistics as well as the econometrician methods have facilitated the introduction the new variables
and factors I the economic growth analysis. In this sense, real variables have mainly been considered in the economic growth
studies, but not financial or risk management aspects. In this sense, it is interesting to analyze the relationship between
economic growth and value at risk and the feed-back process. The goal of the paper is to analyze the relationship between
economic growth and risk management and the feed-back process. We will consider economic variables, including economic growth,
rule of law, human capital, fiscal policy and monetary policy, among others, in our analysis. We will analyze the theoretical
relationships between these variables and risk and the effects of risk on economic growth. We will also develop an empirical
analysis considering the case of 15 European Union countries.

In this paper, we give an example in which the price of tradable emission permits increases despite firms’ adoption of less
polluting technology, a result that is in contrast with Montero (J Environ Econ 44:23–44, 2002) and Parry (J Regul Econ 14:229–254,
1998), among others. If two Cournot players switch to a cleaner technology, the price for permits may increase due to an increase
in the net demand for permits and a decrease in the net supply of permits after the clean technology is adopted. This is only
the case when output demand is quite elastic. 相似文献

Key service innovation drivers in the tourism sector: empirical evidence and managerial implications 总被引:2,自引:2,他引:0

This study highlights the importance of market orientation and the use of information and communication technologies (ICT) as determinants of service innovation activity for companies in the tourism sector. In doing so, the study provides a means to classify companies as innovative or not. Using a sample of 100 Spanish firms from different branches of the tourism sector, we confirm and extend prior research. In particular, market orientation??especially a customer orientation??is critical for developing new services that lead to competitive advantages. In addition, ICT have a dual, direct, and indirect influence on service innovation. 相似文献
