RETAIL PRICE REGULATION AND THE OPTION TO DELAY

ABSTRACT ** :  This paper examines a two-period model of an investment decision in a network industry characterized by demand uncertainty, economies of scale and sunk costs. In the absence of regulation we identify the market conditions under which a monopolist decides to invest early as well as the underlying overall welfare output. In a regulated environment, we consider a monopolist who faces no downstream (final good) competition but is subject to retail price regulation. We identify the welfare-maximizing regulated prices when the unregulated market outcome is set as the benchmark. We show that if the regulator can commit to ex post regulation – that is, regulated prices that are contingent to future demand realization – then regulated prices that allow the firm to recover its total costs of production are welfare-maximizing. Thus, under ex post price regulation there is no need to compensate the regulated firm for the option to delay that it foregoes when investing today. We argue, however, that regulators cannot make this type of commitment and, therefore, price regulation is often ex ante – that is, regulated prices are not contingent to future demand. We show that the optimal ex ante regulation, and the extent to which regulated prices need to incorporate an option to delay, depend on the nature of demand uncertainty.     

Consistent calibration of HJM models to cap implied volatilities

This article proposes a calibration algorithm that fits multifactor Gaussian models to the implied volatilities of caps with the use of the respective minimal consistent family to infer the forward‐rate curve. The algorithm is applied to three forward‐rate volatility structures and their combination to form two‐factor models. The efficiency of the consistent calibration is evaluated through comparisons with nonconsistent methods. The selection of the number of factors and of the volatility functions is supported by a principal‐component analysis. Models are evaluated in terms of in‐sample and out‐of‐sample data fitting as well as stability of parameter estimates. The results are analyzed mainly by focusing on the capability of fitting the market‐implied volatility curve and, in particular, reproducing its characteristic humped shape. © 2005 Wiley Periodicals, Inc.

Cheap home goods and persistent inequality

There exists a large literature which shows that public education is favorable for growth because it increases the level of human capital and at the same time it tends to produce a more even income distribution. More egalitarian societies are also associated with less social conflicts, and individuals have a lower tendency to report themselves happy when inequality is high. Therefore, it is important to study the reasons why the elite opposes the development of a strong public education system. It might be that education is related to social status and a strong public education system might threaten the elite’s political power. We show that one aspect of social status is the specialization of skilled workers in high-paid jobs and the abundance of unskilled workers in the production of cheap “home goods” in the market, such as painting and cleaning a house, babysitting, and/or cooking. We emphasize the role of general equilibrium price adjustments to show that depending on the level of inequality, the elite might prefer an economy with a positive and “high” cost of education than an economy where skills are freely provided. We show that this result goes through even if the skilled wage is not directly affected by the ratio of skilled to unskilled workers. We also provide empirical evidence consistent with our theory.     

Arbitraggi bilanciati per giochi omogenei di maggioranza ponderata

In un gioco omogeneo di maggioranza ponderata le uniche soluzioni « stabili » nel senso di Neumann e Morgenstern sono quelle corrispondenti alla formazione di una qualsiasi coalizione minimale vincente con ripartizione del guadagno solo fra i partecipanti ad essa. Ciò pone dei problemi ad un arbitro chiamato a soddisfare principi di equità per tutti, dando vita allo stesso tempo a situazioni stabili. Presentiamo qui uno schema di arbitraggio probabilistico per giochi omogenei di maggioranza ponderata atto a risolvere, sia pure in ambito incerto, in modo soddisfacente tali esigenze.     

Conservation agriculture practices adopted in southern Brazil

The adoption of conservation agriculture (CA) practices are essential for soil and water conservation. In CA, farmers must adopt no-tillage (NT) with crop rotation to maintain a permanent soil cover. In Brazil, mainly in the South region, for CA to be more efficient, practices such as contour farming and agricultural terraces should also be adopted. Thus, the objective of this study is to determine the extent to which NT has been adopted with crop rotation and others soil and water conservation practices. Data from the Agricultural Census in Paraná State, southern Brazil, were used. For the data analysis, the relationship between the level of adoption of NT and the use of crop rotation, contour farming and agricultural terraces was analyzed. A factor and cluster analysis were performed to distinguish regions in terms of soil and water conservation practices. The results show good overall soil and water conservation practices, although heterogeneity has been observed in the adoption practices between regions. Adoption of NT is high in almost all the studied regions. The conservation practice most widely used with NT is contour farming, whereas the least used is agricultural terraces. Conservation practices for runoff control are being neglected by farmers.     

Assessing Organizational Adoption of Information Systems Outsourcing

The information systems outsourcing (ISO) field continues to grow, as organizations consistently seek improvements in IT activities. The global scope of outsourcing participation and growth leads to gaps of knowledge related to the contextual factors that influence ISO adoption. Using the technology-organization-environment (TOE) framework, this study identifies and contextualizes the determinants of ISO adoption. Data collected from 261 firms suggest that relative advantage, firm size, top management support, and competitive pressure are the main determinants of ISO. This study highlights the importance of assessing ISO using the TOE theoretical lens, and offers replication of prior results, the lack of which is a growing concern in social science research.     

COOPERATIVE FIRMS AND THE CRISIS: EVIDENCE FROM SOME ITALIAN MIXED OLIGOPOLIES

We investigate how cooperative firms reacted to the current crisis. This allows us to compare the behaviour of cooperative and conventional firms facing exogenous shifts in demand. After a short survey of a stream of theoretical literature, we analyze a large group of Italian production cooperatives in the periods 2003–2010 and 1994–2011 and we contrast co‐ops behaviour with the overall trend in the industries in which they operate. Our sample's evidence suggests that the cooperative's behaviour has a stabilizing effect on employment with respect to shocks in output demand. Unlike profit‐maximizers, cooperative firms seem to be adjusting pay more than employment when facing shocks. Production co‐ops look better equipped than their profit‐maximizing counterparts in tackling the long recession also because they have been very cautious in their profit policies over time. Unlike conventional firms, they have significantly increased their own equity during ‘good’ years instead of distributing large dividends to their members.     

Lessons learned from Brazilian multinationals’ internationalization strategies

Internationalization of emerging market multinationals is a recent phenomenon gaining importance in the global economy. This foreign expansion of a new breed of companies has challenged established theories and practices in the field of international business (Cuervo-Cazurra, 2007). This article addresses the issue of whether or not there is something to learn from these emerging market companies and their foreign expansion. Focusing on the international trajectories of four Brazilian multinationals (i.e., Odebrecht, Embraer, Stefanini, and Marcopolo), this study analyzes their strategies and managerial processes during and after the recent economic crisis with regards to internationalization. Our qualitative fieldwork suggests that the trajectories of these Brazilian multinationals are quite unstructured and evolve as a reaction to the opportunities they face in international markets. It seems all four companies in our sample shared a strong entrepreneurial spirit and a high motivation to expand their international operations despite the crisis and the obstacles they faced. Our findings and suggestions in terms of lessons learned should provide valuable implications for multinational managers from other emerging markets by providing a better understanding of how Brazilian multinationals expand internationally, deal with economic crisis, and manage relationships with local and foreign institutions.     

The contribution of macroprudential policies to banks' resilience: Lessons from the systemic crises and the COVID-19 pandemic shock

This study examines the effectiveness of macroprudential policies in reducing the banks' risk during the COVID-19 pandemic and compares these results with the systemic banking crises years. Based on a sample of 624 banks across 40 countries during the period 2006–2020, we find that loosening capital-aimed macroprudential policies effectively reduced banks' risk during the COVID-19 pandemic, while this behavior led to increased risk during the systemic crises years. In contrast, tightening the remaining macroprudential policies during the systemic crises years and during the pandemic proved effective in reducing banks' risk. Furthermore, we show that the magnitude of the impact of macroprudential policies was stronger during the systemic crisis than that during the pandemic. Finally, we show that the results are driven by the capital requirement prudential policy, both during the systemic crisis and the COVID-19 pandemic, although the conservation buffer and the leverage limit also contributes to the ineffectiveness of these policies during the COVID-19 pandemic. The banks' leverage and loan growth also play an enhancing role of the effects of the macroprudential policies.     

Cooperative movement and widespread prosperity across Italian regions

Our goal is to participate in the debate on regional well-being. To this end, we explore the relationship between prosperity and the cooperative movement at the regional level in Italy between 2010 and 2019. We summarize prosperity through an index originally proposed by Amartya Sen and we apply it to classify Italian regions. We then perform panel analyses showing that there is a positive and significant association between such an index and the cooperative presence. We detect that, and explain why, the cooperative movement contributes to the regional prosperity more through its employment than in terms of the added value it generates.
