Using mean-Gini and stochastic dominance to choose project portfolios with parameter uncertainty

Although a variety of models have been studied for project portfolio selection, many organizations still struggle to choose a potentially diverse range of projects while ensuring the most beneficial results. The use of the mean-Gini framework and stochastic dominance to select portfolios of research and development (R&D) projects has been gaining attention in the literature despite the fact that such approaches do not consider uncertainty regarding the projects’ parameters. This article discusses, with relation to project portfolio selection through a mean-Gini approach and stochastic dominance, the impact of uncertainty on project parameters. In the process, Monte Carlo simulation is considered in evaluating the impact of parametric uncertainty on project selection. The results show that the influence of uncertainty is significant enough to mislead managers. A more robust selection policy using the mean-Gini approach and Monte Carlo simulation is proposed.     

Determinants and Dynamics of Current Account Reversals: An Empirical Analysis

We use panel probit models with unobserved heterogeneity, state dependence and serially correlated errors in order to analyse the determinants and the dynamics of current account reversals for a panel of developing and emerging countries. The likelihood‐based inference of these models requires high‐dimensional integration for which we use efficient importance sampling. Our results suggest that current account balance, terms of trades, foreign reserves and concessional debt are important determinants of current account reversal. Furthermore, we find strong evidence for serial dependence in the occurrence of reversals. While the likelihood criterion suggest that state dependence and serially correlated errors are essentially observationally equivalent, measures of predictive performance provide support for the hypothesis that the serial dependence is mainly due to serially correlated country‐specific shocks related to local political or macroeconomic events.     

Shedding light on technological development in Brazil

We try to shed some light on the question of why technology-intensive businesses often fail in less-developed countries and under what circumstances they are likely to be a success from the perspective of both domestic and export markets. The answers were drawn from a set of empirical evidences from Brazilian firms applying photonics technologies. Some of the issues faced by them are related to the question of state versus private initiative, entering traditional versus niche market, and technology transfer versus product development management. In overall, we concluded that weakness of the institutions and inadequacy of social and organizational demography play a key role in explaining to a large extent why countries differ in technological development and diffusion. In this context, we point out obstacles, which must be removed in order to make public policies and firm's achievements more efficient.

From hub to tourist destination – An explorative study of Singapore and Dubai's aviation-based transformation

The growth of air transport networks and deregulation have allowed small, low-populated places like Singapore and Dubai to become major international tourism destinations. Both have used tightly combined airline, airport and tourism strategies to help achieve this. Here we analyse developments in Singapore and Dubai by examining interactions between their airlines, airports, governments and tourism authorities, and how integrated management strategies leveraged their aviation traffic hubs to develop tourism destinations.     

Nonprofit Organizations in Mexico: A Preliminary Study on Knowledge Creation From the Beneficiaries’ Perspectives

ABSTRACT

The purpose of this study is to assess knowledge-creation activities by nonprofit organizations in Mexico from the beneficiaries’ perspectives. The ontological shift Socialization, Externalization, Combination, Interiorization (SECI) model and nonparametric tests were applied to a sample of 429 beneficiaries of 89 nonprofit organizations. The results found socialization was the most important and externalization was the least important aspect of the four types of dynamic knowledge interaction, suggesting an imbalance in knowledge creation, specifically in the conversion from tacit to explicit knowledge, which implies a problem, failure, or explicit barrier between the nonprofit organizations and their beneficiaries. The results further suggest weak links between age and externalization activities, gender and combination activities, and educational attainment and socialization activities. In sum, nonprofit organizations should consider beneficiaries’ individual characteristics when developing activities, disseminating materials, and communicating with the public. The study contributes to our understanding of tacit and explicit knowledge-creation activities by nonprofit organizations in Mexico.     

Early cost management practices, state ownership and market competition: the case of the Royal Textile Mill of Guadalajara, 1717-44

Existing literature on the deployment of cost techniques in early public sector organizations largely relies on archival evidence gathered from late eighteenth and nineteenth-century settings. Arguably, these contexts are characterized by a number of idiosyncratic characteristics that advise caution in generalizing conclusions beyond the institutional elements that forged those settings. Our investigation examines the case of the Royal Textile Mill of Guadalajara (RTM), a setting characterized by state ownership, competitive markets, organization of production around medieval guilds, and recruitment of foreign experts to conduct productive operations. Our findings show that the management of RTM deployed cost accounting techniques that comprised aspects such as control of raw materials and waste, control of labour and management, and allocations of overhead to product costing. We also find evidence which departs from predictions that standards relating to the control of raw materials should have preceded the implementation of labour cost standards.     

Investment option under CIR interest rates

We analyze extensively the characteristics of the solution to an irreversible investment decision when the only source of uncertainty comes from interest rates. They are assumed to be driven by the popular Cox–Ingersoll–Ross (CIR) stochastic process. Particular attention is paid to the impact that both CIR parameters and risk aversion have on the threshold rate.     

The question of land access and the Spanish land reform of 1932

Spanish land reform, involving the breakup of the large southern estates, was a central issue during the first decades of the twentieth century, and was justified on economic and political grounds. This article employs new provincial data on landless workers, land prices, and agrarian wages to consider whether government intervention was needed because of the failure of the free action of markets to redistribute land. Our evidence shows that the relative number of landless workers decreased significantly from 1860 to 1930, before the approval of the 1932 Land reform during the Second Republic (1931–6). This was due to two interrelated market forces: the falling ratio between land prices and rural wages, which made plots of land cheaper for landless workers to rent and buy; and structural change that drained the rural population from the countryside Given that shifts in factor prices were already helping workers gain access to land by the 1930s, the economic arguments for introducing reform at that time remain unclear.
