On the impact of leverage constraints on asset prices and trading volume

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.

Strategic Environmental Standards, Wage Incomes and the Location of Polluting Firms

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.     

Automatic balancing mechanisms for notional defined contribution accounts in the presence of uncertainty

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.     

Value at Risk and Economic Growth

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.

A Note on Clean Technology Adoption and its Influence on Tradeable Emission Permits Prices

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.     

Key service innovation drivers in the tourism sector: empirical evidence and managerial implications

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.     

The effects of perceived value on loyalty: the moderating effect of market orientation adoption

This paper aims to identify the moderating effect of service firms’ adoption of market orientation on key variables of consumer behavior, namely perceived value and loyalty. The study took a business-to-customer perspective. First, the adoption of market orientation was measured, from the firm’s point of view. Second, customer perceptions were analyzed, using the two variables perceived value and loyalty. The sample comprised 100 service firms and 572 of their customers. The present work provides original insights, identifying that the effect of perceived value on loyalty depends on other variables external to the consumer, such as the market orientation approach.     

The role of venture capitalist to enhance the growth of Spanish and Italian university spin-offs

The establishment of spin-offs to commercialise university knowledge/technology is a potential mechanism to promote economic and innovative development. Nevertheless, University Spin-Offs (USOs) are usually resource-constrained, especially in obtaining funding, limiting their growth. Venture Capital (VC) investors play an important role in the financing and the improvement of their managerial skills, which are critical for firm growth. This paper aims to explore both the effect of VC partners on the USOs’ growth and the cross-national differences in the role played by them. To study both issues, we empirically analysed 516 Spanish and 904 Italian USOs created by 50 Spanish and 57 Italian universities, respectively, and observed them between 2005 and 2013. The results showed different effects in the Spanish and Italian cases. While in Spain the presence of VC partners positively affects the USOs’ growth, in Italy there is not a significant effect. This evidence calls for systematic policies by public administrations and universities to foster USO growth.     

Embedding multinational firms in regional business systems: neoliberal and social‐democratic models in Spain

The paper analyses how regional actors have mobilised to attract and retain foreign direct investment in two Spanish regions with different political approaches to the management of economic issues, including industrial relations. These regions are Madrid, the main pole of attraction of foreign direct investment in Spain, and Asturias, with a large tradition of heavy industry and a greater dependence on a small number of large employers. It finds the regions have adapted to international competition in substantially different manners and considers the alternative reasons why this might be the case, highlighting the role of organised labour both in the inward investment regimes themselves, and in shaping the nature of the different compromises they involve.
