Desperately Seeking θ's: Estimating the Distribution of Consumers Under Increasing Block Rates

This paper shows that increasing block rate pricing schedules usually applied by water utilities can reduce the efficiency and equity levels. To do this, we first present a two step method to estimate the demand and to recover the distribution of consumer tastes when increasing block rate pricing is used. We show that in this case the tariff induces a pooling equilibrium and customers with different taste parameters will be observed to choose the same consumption level. Second, we show that a two-part tariff that neither reduces the revenue for the firm nor increases the aggregate level of water consumption increases the welfare and equity levels in relation to an increasing block rates schedule.     

Effects of personal characteristics on organizational commitment: evidence from Brazil's oil and gas industry

In 1997, Brazil's major energy company faced a loss of its monopoly as part of the country's structural reform. Many of its employees were recruited by new entrants to the oil and gas industry. In order to retain employees, the company initiated a multiyear planning process which included a redesigned human resource management model oriented to organizational commitment. This study examines the long-term influence of five employee personal characteristics (type of employment, job level, gender, education level and service time) on the affective, normative and continuance components of organizational commitment. The research was conducted in one of the company refinery and involved a questionnaire survey of all employees and interviews with senior managers. It was found that type of employment (company staff or contractor) had the greatest impact on affective and normative commitment, while service time and education level are the most significant contributors to continuance commitment. Gender and job level were found to have limited implication for commitment. The results demonstrate that the company response to structural reform had the long-term positive effect of binding employees to the organization.     

Towards a configuration of socially responsible human resource management policies and practices: findings from an academic consensus

Abstract

The integration of socially responsible behaviour has become a strategic priority for companies in recent years. Academic contributions that merge the fields of corporate social responsibility (CSR) and human resource management (HRM) have been expanding, demonstrating a broad sweep of benefits reflected in greater levels of commitment, motivation, and performance by employees. However, little has been clarified about what academics and business management understand to be a configuration of socially responsible human resource management (SR-HRM) practices. This paper aims to define and provide an initial academic approximation of a set of socially responsible human resource practices. In order to accomplish this objective, a content analysis was conducted based on a review of the literature, CSR reports, and international CSR standards such as the Global Reporting Initiative and ISO 26000. The theoretical findings were supported by a panel of experts who inspected them over three rounds of reviews. The sample for the study was created by consulting the academic literature, strengthened by the input from the panel of experts. The results show an academic consensus of 80%, and support the existence of a valid configuration of 8 socially responsible human resource policies divided into 32 practices.     

Strategic Versus Tactical Nature of Sales Promotions

Sales promotions (SP) are short‐term instruments usually designed to yield an immediate sales effect. Previous research has suggested that SP can be seen as detrimental to a brand's consumer franchise/equity as, in the long term, SP deteriorates brand value. In this paper, we theoretically broaden the scope of SP research relation to the following topics: strategy concept, marketing strategy, the Integrated Marketing Communication (IMC) concept, the specific nature of each SP instruments and the underlying processes associated with consumer uptake of SP. We present findings that illustrate managers' perceptions of the positioning of SP instruments. We argue that the strategic nature of SP needs to be incorporated into marketers' research agendas.     

Domestic transport infrastructure and firms’ export market participation

Investment in transport infrastructure reduces the cost of distance and enables firms to establish contacts over larger distances. Using data from a panel of Spanish manufacturing firms and geographic information system techniques, this article studies the impact of domestic transport cost reductions on firms’ export market participation, taking into account the role of entry costs and other firm characteristics. We estimate dynamic probability models, controlling for the unobserved heterogeneity of firms and for the simultaneity of firms’ export and location decisions. Our results demonstrate a positive effect of domestic transport infrastructure improvements on small and medium-sized firms’ probability of exporting.     

High-speed rail transport valuation

In this paper, the optimal timing for investing in high-speed rail projects under uncertainty in relation to the utility provided to railway users was investigated. To accomplish this, a continuous time real options analysis framework using a stochastic demand model was developed to determine the optimal time to invest. Uncertainty upon investment expenditures was also added in an extended framework. The value of the option to defer and the investment opportunity value were also assessed.     

Long-term bank balance sheet management: Estimation and simulation of risk-factors

We propose a dynamic framework which encompasses the main risks in balance sheets of banks in an integrated fashion. Our contributions are fourfold: (1) solving a simple one-period model that describes the optimal bank policy under credit risk; (2) estimating the long-term stochastic processes underlying the risk factors in the balance sheet, taking into account the credit and interest rate cycles; (3) simulating several scenarios for interest rates and charge-offs; and (4) describing the equations that govern the evolution of the balance sheet in the long run. The models that we use address momentum and the interaction between different rates. Our results enable simulation of bank balance sheets over time given a bank’s lending strategy and provides a basis for an optimization model to determine bank asset–liability management strategy endogenously.     

Changing returns to education in Portugal during the 1980s and early 1990s: OLS and quantile regression estimators

This paper examines the evolution of the returns to education in Portugal over the 1980s and early 1990s. The main findings indicate that the returns to education have increased, particularly after joining the European Union in 1986. Since this occurred along with an increase in the level of education within the labour force, the process is most likely demand driven. The results also indicate that modelling on average (i.e. OLS) misses important features of the wage structure. Quantile regression (QR) analysis reveals that the effect of education is not constant across the conditional wage distribution. They are higher for those at higher quantiles in the conditional wage distribution. Wage inequality expanded in Portugal over the 1980s and the returns to education had an important role in this process.     

Regional mobility in the European Union

Regional mobility in the spatial distribution of per capita income in the European Union is examined over the period 1977 to 1999. The methodology used to investigate this issue combines a series of measures taken from the literature devoted to the dynamic study of personal income distribution with a non-parametric analysis. The results show limited mobility in the distribution considered, and a decline in mobility over time. The empirical evidence presented indicates, moreover, that mobility patterns vary as a function of regional development levels. Additionally, the analysis carried out investigates the role played in explaining intra-distribution mobility by variables such as per capita income, population density, per capita expenditure in investment, market potential, and the share in total employment of agriculture, advanced services and non-market services.
