How do telecommunications reforms affect labour market arrangements? Evidence from Central and Western Europe

This paper exploits variations in the timing of telecommunications reforms across Europe to investigate the relationship between the rise of alternative work arrangements and the emergence of the Internet. We evaluate whether sectors that are technologically more dependent on information and communication technologies (ICT) experienced disproportionately larger changes in their employment outcomes after telecommunications reforms were introduced. Our main results point to a disproportionate increase in total employment, part‐time work and home‐based work among ICT‐dependent sectors after the implementation of telecommunications reforms. These results suggest that telecommunications reforms affected labour market arrangements by fostering the adoption of ICT. The results are robust to several specifications.     

Synchronization and diversity in business cycles: a network analysis of the European Union

In this article, we use a correlation matrix and its internal networks to analyse business cycle synchronization across Europe since 2000. This methodology allows us to summarize individual country interactions and co-movements while also capturing the existing heterogeneity of connectivity within the European economic system. Our results indicate that synchronization of the euro zone countries remained stable from 1999 until the current financial crisis, after which co-movements increased sharply and synchronization rose to the highest in the time sample. By endogenously identifying clusters of countries with close connections in their business cycle, we also refute the commonly accepted notion of identifiable core and peripheral euro zone countries.     

The new leader's guide to diagnosing the business

Incoming CEOs and general managers don't have much time to show what they can do to improve a business's performance. (In 2006, for instance, about 40% of CEOs who left their jobs had lasted an average of just 1.8 years--and many of them were ushered out the door.) Within a few years at most, leaders must find ways to boost profitability, increase market share, overtake a competitor--whatever the key tasks may be. But they can't map out specific objectives and initiatives until they have accurately assessed their companies' distinctive strengths and weaknesses and the particular threats and opportunities they face. In this article, Bain consultants Gottfredson, Schaubert, and Saenz provide a diagnostic template to help organizations figure all that out so they can decide which goals are reasonable and where to focus performance-improvement efforts. The template is built on four widely accepted principles. First, costs and prices almost always decline; second, your competitive position determines your options; third, customers and profit pools don't stand still; and fourth, simplicity gets results. Along with each principle, the authors offer diagnostic questions and analytic tools. Of course, each manager will emphasize certain elements of the template and de-emphasize others, based on his or her business situation. This process will show incoming CEOs and general managers where they are starting from (their point of departure) and help them establish their performance objectives (their point of arrival) as well as the change initiatives that will take them where they want to go.     

Status Differentiation and the Protean Self: A Social-Cognitive Model of Unethical Behavior in Organizations

Based on social-cognitive theory, this article proposes a model that seeks to explain why high status organizational members engage in unethical behavior. We argue that status differentiation in organizations creates social isolation which initiates activation of high status group identity and a deactivation of moral identity. We further argue that high status group identity results in insensitivity to the needs of out-group members which, in turn, results in lessened motivation to self-regulate ethical decision making. As a result of this identity activation, we demonstrate how high status individuals will be more vulnerable to engaging in unethical activities. Individual-level moderators of the relationships are also discussed.     

Uncovering the relationship between workaholism and workplace destructive and constructive deviance: an exploratory study

Given the significant social and economic costs and/or benefits associated with workplace deviance, researchers have been interested in examining the antecedents of deviant behaviour. Similarly, as the incidence of workaholism has increased, there has been a need to further understand the positive and negative consequences of workaholism in an organizational context. This exploratory study examined the relationship of three workaholism components with measures of workplace destructive and constructive deviance. Data were collected from 142 male and female employees working in six companies in Brazil using anonymously completed questionnaires. The results suggest that the workaholism components were significantly related to two measures of deviance. This provides partial support for the hypothesized relationship. Future research directions and practical implications are discussed.     

Price elasticity of demand for broadband: Evidence from Latin America and the Caribbean

In this study the authors analyze fixed broadband retail prices in Latin America and the Caribbean (LAC), and provide estimates about the effect of price changes on broadband adoption. The analysis is based on a survey of plans and tariffs conducted by the authors during Q2 2010. Their results suggest that fixed broadband services in LAC are generally expensive and of poor quality when benchmarked against Organisation for Economic Co-operation and Development (OECD) countries, although there is significant variance between markets in the region. In order to isolate the effect of prices on broadband adoption they use an instrumental-variable approach. Their findings show that broadband demand is relatively elastic to price in LAC but not in the OECD. They estimate that an average price reduction of 10% would result in an increase of almost 22% in the penetration rate in LAC, equivalent to almost 8.5 million additional broadband connections. Several policy implications result from these findings. First, national broadband policies in LAC should pay a closer attention to a deficit of competition in fixed broadband services, as households and firms face high prices for poor quality services, thus deterring adoption. Second, while their findings generally suggest that price reductions could significantly increase penetration, they elasticity estimates reveal that price effects might not be sufficient to achieve the penetration goals set in national broadband plans. This validates the need for complementary policy strategies that affect other determinants of broadband demand. The example of Brazil is used to illustrate this finding.     

Hybrid conjoint analysis: An estimation probe in new venture decisions

How venture capitalists select start-ups for financing has been an interesting topic for many researchers and practitioners. The underlying assumption is that people who make money investing in new businesses by assessing the proposals should be experienced enough to distinguish losers from winners. Our research study tested three models (self-explicated, conjoint and a hybrid—comprising the two previous ones—conjoint) in order to find out: 1. if these models could be applied to venture capital decision making and if so 2. to demonstrate the potential of conjoint analysis as a practical research method. 3. To test whether or not the characteristics of the entrepreneur, the product and the market replicate the venture capital decision.This research study confirms what normative literature on decision-making emphasizes: that in the first stage of an evaluation (screening), venture capitalists focus on a small subset of criteria in a non-compensatory process (i.e., an unacceptable value on one criterion cannot be offset by a high value of another one). The important criteria in this phase appear to be the entrepreneur's experience and the existence of a prototype for some decision-makers or unique features of the product for others. The screening step is more judgemental than analytic.In a second stage (the evaluation phase), however, venture capitalists end a detailed examination (due diligence process) by choosing the most preferred ventures through processes approximating compensatory rules; that is, a low but acceptable value on one criterion can be compensated by a high value on another. The most important criteria identified by the research in this second stage are criteria found in the previous stage, product gross profit margin and patent.Our research demonstrates agreement among venture capitalists in terms of one criterion to evaluate research proposals: managerial experience. As to the rest of the attributes tested, there was variation in the weights assigned to them.The findings of this pilot study also confirm the applicability of conjoint analysis as a research method in venture capital decision. The approach helps shed light on the decision rules applied, and permits the testing of previously researched criteria for predictive validity. The method has the advantage of retaining individual preferences and clustering them around venture capitalists' demographic and psychographic backgrounds (i.e., years of experience, type of education, life-style, and the like) or other types of information such as venture fund policies (size of the investment, type of industry, etc.).The major implication of the study for entrepreneurs is the importance of previous experience in the industry where they expect to develop their ventures, and a deep knowledge of the product (advantages over competition, technical, production, and cost feasibility) they are to produce and market. These are the factors that have the greatest influence on venture capitalists' evaluation of such projects.     

Dynamic multiproduct optimal hedging in the soybean complex – do time-varying correlations provide hedging improvements?

Optimal multiproduct time-varying hedge ratios are determined – for a soybean complex – and their risk-mitigating impact is contrasted over single-commodity time-varying and naive hedge ratios. A parsimonious regime-switching dynamic correlation model is employed, with the estimated dynamic correlation matrix among prices varying between two different levels, and the time-varying correlations being applied to the multiproduct setting. Findings obtained are three-fold. First, there is significant evidence that estimated simultaneous correlations among different commodities’ prices (e.g. soybean spot and soybean meal futures) attain different values along the time series. Second, there is a substantial reduction in margin variance provided by the optimal multiproduct time-varying hedge ratios over single time-varying and naive hedge ratios, for both in- and out-of-sample data. Third, average optimal multiproduct time-varying hedge ratios for soybean and soybean meal (0.82 and 0.74, respectively; for out-of-sample data) are significantly below the naive full hedge ratio, providing risk mitigation at lower costs.     

Financial structure,informality and development

The impact of capital market imperfections and costs of creating and operating formal sector firms on total factor productivity is studied. We propose a firm dynamics model with endogenous formal and informal sectors where firms face a technology adoption opportunity. The model predicts that countries with a low degree of debt enforcement and high costs of formality are characterized by low allocative efficiency and large output shares produced by low productivity, informal sector firms. For frictions parametrized using the Doing Business database, the model generates a drop in total factor productivity of up to 25% relative to the US.     

An empirical assessment of metaphor use in the design studio: analysis, reflection and restructuring of architectural design

This investigation was concerned with the use of metaphors in architectural design education. Reasoning by means of metaphors helps to understand a design situation in terms of a remote concept normally not associated with it. By juxtaposing the known with the unknown in an unusual way, metaphors can enhance design problem solving. The goal of this study was to research empirically the use of metaphors in the design studio as perceived by students. By analyzing relations between metaphorical reasoning and design, we explored metaphor factors that have a major contribution to the design process. Results showed that ‘Restructuring design problems’ and ‘Delving into design solutions’ are the main factors of design problem solving. Furthermore, ‘Innovative design based on personal beliefs’ and ‘Analysis and reflection on design problems’ are the two factors associated with metaphor use. The latter was found to be a significant predictor with a contribution to ‘Restructuring of design problems’. Findings have implications for design education, particularly for intervention programs that seek to improve reasoning and reflection skills in the architectural design studio.
