This paper highlights the difficulty of developing HT firms in a peripheral region of Spain. Although the endogenous development of HT firms in these regions is possible, their evolution depends on more central regions. The firm's geographical location and the type of HT production are the most important endogenous factors governing the firm's success. 相似文献

消费问题经过几十年的讨论,至今仍没有得到一些人的高度重视。重投资,重GDP的增长,不重视消费拉动的老毛病,一直制约着我国经济的可持续发展。事实上,如果我国消费水平再不上一个新台阶,还将制约我国经济的持续发展。应该将扩大消费需求提升到我国发展的战略高度来认识。一、应 相似文献

Telecommunication services have existed as a legal monopoly nearly throughout its entire history. In 1998, telecom market liberalisation was achieved across the European Union (EU) through the introduction of competition among telephone services. Asymmetrical obligations were deemed necessary in order to compensate the market power of the former monopolist.As the evolution of asymmetrical regulation in Spain illustrates, obligations and the telecommunications operators subject to them increased with the regulatory framework established in 2002 in the EU. This new regulatory framework may continue to expand through the inclusion of functional separation as another possible asymmetrical obligation. In short, it seems that the regulatory pressure on the telecommunications industry is increasing, despite the lapse in time since the liberalisation of the industry.In this paper, a methodology developed by the Austrian School of Economics is applied in order to explain why the telecommunication market is subject to increasing regulation in Europe, rather than deregulation, after more than 10 years of liberalisation. In particular, Mises's theory of price control is used to explain the evolution of the regulation of local loop unbundling. 相似文献

In the process of coding open-ended questions, the evaluation of interjudge reliability is a critical issue. In this paper,
using real data, the behavior of three coefficients of reliability among coders, Cohen’s K, Krippendorff’s α and Perreault and Leigh’s I
r
are patterned, in terms of the number of judges involved and the categories of answer defined. The outcome underlines the
importance of both variables in the valuations of interjudge reliability, as well as the higher adequacy of Perreault and
Leigh’s I
r
and Krippendorff’s α for marketing and opinion research. 相似文献

We analyze the impact of product diversification on performance. This topic has been discussed in the literature, and there
is no consensus so far as to the significance or the direction of the impact. Performance is measured using Tobin's q for
a sample of 103 large, non-financial Spanish firms (1992–1995). Diversification is measured by means of a categorical variable,
as suggested by Varadarajan. The principal results indicate that the firms with intermediate levels of product diversification
have the highest performance, while the firms with low and high levels of diversification show significantly lower performance,
which performance is not significantly different between them. 相似文献

A new framework is presented for the study of the existence and uniqueness of solutions to the Koopmans’ equation in the unbounded
case, that is based on the contraction mapping approach. In the bounded below case with bounded consumption streams, uniqueness
of the solution in the whole class of weak-star continuous utility functions is obtained. When the aggregator is unbounded
below and/or consumption streams are unbounded, existence of a weak-star continuous solution is shown, and a simple criterium
to check the sufficient conditions for existence is provided.

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.
