Services for the underserved: unintended well-being

There is a lack of research on service consumption practices of Base of the Pyramid consumers. This study contributes to the Transformative Service Research agenda by understanding stigmatized service consumption practices and their effect on the well-being of these consumers; this has not been fully addressed until now. Additionally, it is shown that understanding the relations among consumers, communities, and informal service offerings results in the design of services with unintentional positive effects on well-being at individual, collective, and relational levels. Findings show that informal service offerings are non-discriminatory, hassle-free, jargon-free, and reputation-based. These findings pave the way to further explore such complex contexts to better understand the impact of service design on the well-being of such consumers. Positive practices can be adopted by any service industry that intends to serve that segment through the intentional redesign of offerings that are engaging, inclusive, and simple and acknowledge social standing.     

Improving the “Leader–Follower” Relationship: Top Manager or Supervisor? The Ethical Leadership Trickle-Down Effect on Follower Job Response

Since time immemorial, the phenomenon of leadership and its understanding has attracted the attention of the business world because of its important role in human groups. Nevertheless, for years efforts to understand this concept have only been centred on people in leadership roles, thus overlooking an important aspect in its understanding: the necessary moral dimension which is implicit in the relationship between leader and follower. As an illustrative example of the importance of considering good morality in leadership, an empirical study is conducted in which a good performance of the “leader–follower” relationship is reflected when individuals perceive ethical leadership in higher hierarchical managerial levels. To be precise, findings of this study demonstrate that follower job response is improved through an ethics trickle-down partial effect from the Top Manager to the immediate supervisor, and also reveal both key aspects and managerial level on which the practice of ethical leadership should rest upon to have a stronger effect on the follower positive job response. Practical implications of these findings and directions for future research are finally presented.     

Revisiting the decomposition of cost efficiency for non-homothetic technologies: a directional distance function approach

In the early 1980’s Kopp and Diewert proposed a popular method to decompose cost efficiency into allocative and technical efficiency for parametric functional forms based on the radial approach initiated by Farrell. We show that, relying on recently proposed homogeneity and duality results, their approach is unnecessary for self-dual homothetic production functions, while it is inconsistent in the non-homothetic case. By stressing that for homothetic technologies the radial distance function can be correctly interpreted as a technical efficiency measure, since allocative efficiency is independent of the output level and radial input reductions leave it unchanged, we contend that for non-homothetic technologies this is not the case because optimal input demands depend on the output targeted by the firm, as does the inequality between marginal rates of substitution and market prices—allocative inefficiency. We demonstrate that a correct definition of technical efficiency corresponds to the directional distance function because its flexibility ensures that allocative efficiency is kept unchanged through movements in the input production possibility set when solving technical inefficiency, and therefore the associated cost reductions can be solely—and rightly—ascribed to technical-engineering-improvements. The new methodology allowing for a consistent decomposition of cost inefficiency is illustrated resorting to simple examples of non-homothetic production functions.     

Entrepreneurial attributes for success in the small hotel sector: a fuzzy-set QCA approach

By examining small hotels in Spain, this research contributes to understanding how human capital, social capital, and contingency factors interact to build a success model based on high hotel occupancy rates, profit, and profit per employee. Human capital theory, social capital theory, and multilevel theory provide the theoretical basis for this research. The study used fuzzy-set qualitative comparative analysis applied to a sample of 51 small Spanish hotels. The results reveal the existence of different configurations that lead to the desired performance outcomes. Each configuration combines two or three causal conditions. The results also reflect the difficulties that small hotels may face in reconciling different performance objectives. This paper thus provides solutions for managers, who must make strategic decisions based on existing conditions both inside and outside their organisations. The findings discussed herein can thus help small hotels better define their performance objectives by considering their individual characteristics. The findings can also help new small hotel entrepreneurs better understand the conditions required for success in this highly competitive market.     

A quality approach to airport management

This paper discusses aspects of airport service quality evaluation using fuzzy multicriteria analysis and the alpha-cut concept. It presents a fuzzy multicriteria methodology for analysing a complex set of quality variables. This methodology develops a step by step set of indicators that allow managers have a holistic view of the quality dimension. It also helps the understanding of cause and effect relation, it helps tracking service quality problems and benchmarking them. From the alpha-cut concept, by defining upper and lower limits, this approach seeks to assist managers in evaluating a complex number of quality criteria and decision-makers’ behaviour. This approach gives managers a broader view of comparative perceptions of quality among the airports in a given sample, by presenting the results of the analysis in fuzzy form and allowing managers to consider different styles of evaluation. The methodology discussed is applied to six Brazilian international airports.     

What are the effects of fiscal policy on asset markets?

We investigate the link between fiscal policy shocks and asset markets. Our results show that spending shocks have: a positive and persistent effect on GDP in the U.S. and in the U.K., while for Germany and Italy, such impact is temporary; a positive and persistent effect on housing prices; a negative effect on stock prices; and mixed effects on the price level. A VAR counter-factual exercise suggests that fiscal shocks play a minor role in the asset markets of the U.S. and Germany, and substantially increase the variability of housing and stock prices in the U.K., while government revenue shocks have increased volatility in Italy.     

How Does Fiscal Consolidation Impact on Income Inequality?

In this paper, we assess the impact of fiscal consolidation on income inequality. Using a panel of 18 industrialized countries from 1978 to 2009, we find that income inequality significantly rises during periods of fiscal consolidation. In addition, while fiscal policy that is driven by spending cuts seems to be detrimental for income distribution, tax hikes seem to have an equalizing effect. We also show that the size of the fiscal consolidation program (in percentage of GDP) has an impact on income inequality. In particular, when consolidation plans represent a small share of GDP, the income gap widens, suggesting that the burden associated with the effort affects disproportionately households at the bottom of the income distribution. Considering the linkages between banking crises and fiscal consolidation, we find that the effect on the income gap is amplified when fiscal adjustments take place after the resolution of such financial turmoil. Similarly, fiscal consolidation programs combined with inflation are likely to increase inequality and the effects of fiscal adjustments on inequality are amplified during periods of relatively low growth. Our results also provide support for a non‐linear relationship between inequality and income and corroborate the idea that trade can promote a more equal distribution of income.     

Machine learning advances for time series forecasting

In this paper, we survey the most recent advances in supervised machine learning (ML) and high-dimensional models for time-series forecasting. We consider both linear and nonlinear alternatives. Among the linear methods, we pay special attention to penalized regressions and ensemble of models. The nonlinear methods considered in the paper include shallow and deep neural networks, in their feedforward and recurrent versions, and tree-based methods, such as random forests and boosted trees. We also consider ensemble and hybrid models by combining ingredients from different alternatives. Tests for superior predictive ability are briefly reviewed. Finally, we discuss application of ML in economics and finance and provide an illustration with high-frequency financial data.     

What is the impact of wealth shocks on asset allocation?

I test the assumption of constant relative risk aversion using U.S. macroeconomic data and analyse the role of wealth shocks in generating transitory changes in asset portfolio composition. I show that the risky asset share exhibits cyclical behavior and it is significantly (and positively) affected by unexpected variation in wealth. Therefore, the empirical evidence suggests that risk aversion is counter-cyclical. I also find that the portfolio share of housing wealth falls when the agent is faced with a positive wealth shock, i.e. housing is a hedge against unfavorable wealth fluctuations. Finally, considering a variety of wealth definitions, the results show that: (i) wealth effects are stronger for direct holdings of risky assets than for indirect holdings, which highlights that investors do not typically trade some assets such as pension or mutual funds; (ii) although significant, wealth effects on asset allocation are mainly temporary as agents quickly rebalance the asset portfolio composition (i.e. there is weak evidence of inertia or slow adjustment in asset allocation); and (iii) changes in expected returns partially explain the variation in risky asset allocation.     

The Determinants of the Volatility of Fiscal Policy Discretion

This paper investigates the determinants of the volatility of fiscal policy discretion. Using a linear dynamic panel data model for 113 countries from 1980 to 2006 and a system‐GMM estimator, we find that an increase in the number of episodes of government crisis, less democracy and presidentialist systems raise the volatility of the discretionary component of fiscal policy. Additionally, we show that countries with larger populations and less flexible exchange rate systems are more insured against uncertainty about the conduct of fiscal policy. Our results are robust to various regional dummy variables, different subsets of countries and the presence of high inflation and crisis episodes.
