Asymptotic inference for a one-dimensional simultaneous autoregressive model

A nonstationary simultaneous autoregressive model \({X^{(n)}_k=\alpha \Big(X^{(n)}_{k-1}+X^{(n)}_{k+1}\Big)+\varepsilon_k, k=1, 2, \ldots , n-1}\), is investigated, where \({X^{(n)}_0}\) and \({X^{(n)}_n}\) are given random variables. It is shown that in the unstable case α = 1/2 the least squares estimator of the autoregressive parameter converges to a functional of a standard Wiener process with a rate of convergence n ², while in the stable situation |α| < 1/2 the estimator is biased but asymptotically normal with a rate n ^1/2.     

Noncentral bimatrix variate generalised beta distributions

In this paper, we determine the density functions of nonsymmetrised doubly noncentral matrix variate beta type I and II distributions. The nonsymmetrised density functions of doubly noncentral and noncentral bimatrix variate generalised beta type I and II distributions are also obtained.     

Estimation of poverty measures with auxiliary information in sample surveys

The analysis of poverty measures has been receiving increased attention in recent years. This paper contributes to the literature by developing percentile ratio estimators based on the pseudo empirical likelihood method. In practice, variances of poverty measures could be not expressible by simple formulae and consequently other techniques should be used in the variance estimation stage. Assuming percentile ratios, resampling techniques are investigated in this paper. A numerical example based on data from the Spanish Household Panel Survey is taken up to illustrate how suggested procedures can perform better than existing ones. The effect of a model-misspecification on the proposed estimators is also evaluated by using simulated populations.

Network embeddedness,headquarters entrepreneurial orientation,and MNE international performance

The aim of this paper is to examine the role played by external and internal network embeddedness in the headquarters entrepreneurial orientation of multinational enterprises (MNEs), and the role of the latter in MNE performance. Drawing on responses from CEOs in a sample of 143 European MNEs, our study offers evidence for the antecedent role of network embeddedness on headquarters entrepreneurial orientation on the one hand, and for the positive impact of headquarters entrepreneurial orientation on international performance on the other. Our findings contribute to the network view of MNEs in the international business and international entrepreneurship literature by disentangling the complex phenomenon of entrepreneurship in MNEs, partly explained by its multiple embeddedness in external and internal networks, and by studying its impact on international performance.     

Urban transformation and diffusion of tourist practices: visiting Alcântara at the turn of the twentieth century

This article examines the effects of tourism on the transformation of the perception of the urban world. I aim at exploring the role that tourist practices have played in the evolution of the organisation and uses of urban spaces or, in other words, in the way the city has been experienced and lived. The development of tourist practices and situations has contributed to framing the discontinuous progress of urbanisation. To better understand this process, I propose to move beyond exploration of specific tourist contexts and places, and to think about the complex relationship between, on the one hand, the material and social arrangements of the city, and on the other, the discourses and representations produced around it. My research draws on a specific case study, namely: The transformation of representations of the Alcântara neighbourhood in turn-of-the-century Lisbon, from an industrial suburb to a popular and ‘urban’ place [Vidal, F. (2006). Les habitants d'Alcântara. Histoire sociale d'un quartier de Lisbonne au début du XXe siècle [The inhabitants of Alcântara. A social history of a Lisbon neighbourhood in the early twentieth century]. Villeneuve d'Ascq: Presses Universitaires du Septentrion]. During the turn to the twentieth century, Alcântara became ‘visible’ and ‘visitable’. The former industrial suburb was thenceforth perceived as a pleasant and urban place, both in a practical way (patent, for example, in the experience of walking down the streets or of visiting industrial sites) and in a symbolic way (through the construction of neighbourhood identities and heritage policies).     

Does fiscal policy influence monetary policy? The case of Spain, 1874-1935

The Spanish peseta never formally belonged to the gold club, neither the classical nor the exchange-rate gold standards. It has been traditionally argued that the reason was the predominance of deficits in the Spanish budget from 1874 to 1935. The financing needs of the Treasury led to money creation and, consequently, to sacrificing the gold commitment and a fixed exchange rate. Applying a stationary VAR (Vector AutoRegressive) model, this paper estimates the dynamic link between budget and money and tests whether Spanish fiscal policy actually influenced monetary policy. The results confirm the dominance of fiscal policy for the period and, therefore, provide empirical support to the idea that the problems of the Treasury were behind Spain’s renouncement of gold.     

Rate of Return Regulation: The Case of Spanish Ports

An original model is put forward in this article to explain and consider the behavior of some of the most important public services in Spain. The cost function approach and the input distance function approach are used to estimate the existence of overcapitalization as a result of rate of return regulation. The results show that overcapitalization generated by this regulation is too significant not to be taken into account.
