Excel spreadsheet as a tool for social narrative analysis

Qualitative research is an open field where different researchers from several disciplines deal with social meanings and with the issue of understanding. During the last two decades, the use of computers and software has extended to become a relevant part of our daily landscape and also a basic device of social research, even in relation to a qualitative approach. There are many applications of qualitative research software specially designed by a diversity of firms and institutions producing different levels of sophisticated tools that can be used in the social research process. This paper presents a protocol for using an Excel spreadsheet as a tool for analyzing social discourses. We will show how to work with the documents produced in the empirical data collection and the criteria to structure the components of the application and its main representations. Finally, we offer a methodology for developing a personalized application in order to orient social design as a powerful and reflexive tool that contribute to a social thinking immersed in continuous improvement.     

ON THE IMPACT OF FUNDAMENTALS,LIQUIDITY, AND COORDINATION ON MARKET STABILITY*

We develop a coordination game to model interactions between fundamentals and liquidity during unstable periods in financial markets. We then propose a flexible econometric framework for estimation of the model and analysis of its quantitative implications. The specific empirical application is carry trades in the yen–dollar market, including the turmoil of 1998. We find a generally very deep market, with low information disparities among agents. We observe occasional episodes of market fragility or turmoil with up by the escalator, down by the elevator patterns in prices. The key role of strategic behavior in the econometric model is also confirmed.     

EMPLOYMENT PROTECTION AND THE NON‐LINEAR RELATIONSHIP BETWEEN THE WAGE‐PRODUCTIVITY GAP AND UNEMPLOYMENT

This paper studies the relationship between the wage‐productivity gap and the unemployment rate in OECD countries between 1985 and 2007. In particular, we investigate whether differences in the employment protection across countries affect the link between these two variables. We show that the elasticity of unemployment with respect to the wage‐productivity gap is non‐linear and that it switches from a positive to a negative value with stricter employment legislation. From a theoretical point of view, we argue that this result is related to a set of labor market reforms introduced in many OECD countries, which affected the relative strictness of institutions.     

Remittances and banking sector breadth and depth: Evidence from Mexico

Despite the importance of remittances to developing countries, their impact on banking sector breadth and depth in recipient countries has been largely unexplored. We examine this topic using municipality-level data on the fraction of households receiving remittances and on measures of banking breadth and depth for Mexico. We find that remittances are strongly associated with greater banking breadth and depth, increasing the number of branches and accounts per capita and the amount of deposits to GDP. These effects are significant both statistically and economically, and are robust to the potential endogeneity of remittances, inclusion of a wide range of controls and even municipal fixed effects specifications using an alternative panel data set from a sample of municipalities.     

Optimal collusion under cost asymmetry

Cost asymmetry is generally thought to hinder collusion because a more efficient firm has both more to gain from deviations and less to fear from retaliation than less efficient firms. Our paper reexamines this conventional wisdom and characterizes optimal collusion without any prior restriction on the class of strategies. We stress that firms can credibly agree on retaliation schemes that maximally punish even the most efficient firm. This implies that whenever collusion is sustainable under cost symmetry, some collusion is also sustainable under cost asymmetry; efficient collusion, however, remains more difficult to sustain when costs are asymmetric. Finally, we show that in the presence of side payments cost asymmetry facilitates collusion.     

Dependent self-employment as a way to evade employment protection legislation

This paper examines whether the strictness of employment protection legislation encourages employers to contract out work to their own paid employees by the formula of dependent self-employment, while making transitions to independent self-employment less likely by altering the relative valuation of risk between salaried work and self-employment in favour of the former. In conducting this analysis, discrete choice models are applied to data drawn from the European Community Household Panel from 1994 to 2001. To test the hypotheses, a tentative individual measure of the potential severance payment that a worker would receive in the case of dismissal is included as well as aggregated variables that try to capture differences in labour market institutions and macroeconomic conditions. Evidence for a positive impact of the strictness of employment protection legislation and the potential severance payment on transitions to dependent self-employment is found. The opposite effects, however, are detected for individuals becoming independent self-employed.     

HOUSEHOLDS’ BEHAVIOUR AND ENVIRONMENTAL EMISSIONS IN A REGIONAL ECONOMY

Households have significant demand-side potential to drive reductions in atmospheric emissions, including both direct and indirect emissions. Our analysis focuses on the behaviour of a regional economy (Aragon, Spain) and its impact on greenhouse gases (GHG) and sulphur dioxide (SO₂). Using a CGE model, we simulate scenarios and evaluate the environmental impact of adopting changes considered in the Aragonese Climate Change and Clean Energy Strategy. Specifically, we analyse the impact of electricity savings and the promotion of public transport (bus or train) versus private car use. The results indicate that 1 MWh of saving in electricity consumption by households could reduce emissions of GHG by 0.112 kt of equivalent CO₂ and 8.209 kg of SO₂ with a shift in demand preferences and 0.022 kt of equivalent CO₂ and 7.612 kg of SO₂ with an efficiency improvement. Moreover, household changes in demand preferences regarding private/public transport, also contribute to reduce emissions.     

Modelling demand and supply influences on utilization: A flow demand model to predict hospital utilization at the small area level

This study outlines a model to predict hospital utilization at the small area level within a National Health Service (NHS) institutional context. The proposed approach departs from alternative analyses based on utilization flows of hospital care between a local population and a hospital. A flow demand model is outlined that relates flow demand to utilization flows; models the interaction between hospital supply and utilization of alternative hospitals; captures the process of demand for hospital care, with special attention given to the role of other health care sectors, to the organizational and institutional context of the hospital system and to geographic variations. The flow approach partly overcomes the problem of dealing with simultaneity of determination between supply and demand. A two-part econometric model suitable to estimate the flow demand model for prediction purposes is tested and applied to the Portuguese health care system. The results show the model to be robust and to provide key information for defining future hospital policies at the central level.
