Differential risk premiums and the UIP puzzle

We respecify the uncovered interest rate parity (UIP) conditions by inverting the market price of the risk (Sharpe ratio) formula. Our empirical model provides new insight indicating that violations to the UIP stem from the existence of a risk premium in the exchange rates and from observed market return differentials being a noisy statistic of the markets’ expected return differentials in our respecified model. Using an integrated macro‐micro structure framework for expected market return differentials improves our model fit and the validity of UIP.     

Discretionary enforcement and strategic interactions between enforcement agencies and firms: a theoretical and laboratory investigation

This paper presents a game theoretic morphological analysis of the strategic interactions between environmental enforcement authorities and polluting firms. The models explore the role of discretion that such authorities enjoy, either in deciding how to pursue environmental violations (investigative and prosecutorial discretion) or in judging them (judicial discretion). The purpose is to identify both the optimal firms’ behaviour in terms of compliance, and the enforcement authorities’ optimal strategies in terms of enforcement actions to undertake. Consistent with the setting of the game theoretic models, the role of the enforcement agencies in deterring firms from polluting is, then, empirically tested by means of laboratory experiments. Laboratory evidence on compliance behaviour of firms when faced with enforcement conditions predicted by the theoretical models set up is discussed for the different experimental treatments performed. Overall, we suggest that making environmental enforcement less predictable for the firms, and thus creating a degree of uncertainty for the violators, can actually encourage deterrence and, thus, improve compliance. Thus, a partly unpredictable enforcement strategy may generate more compliance than an environmental policy that is known with certainty in advance.     

Assessing and predicting financial vulnerability of Italian households: a micro-macro approach

In this study we develop a micro-founded model to analyse the economic-financial conditions of Italian households. Using household level data, we build an indicator to identify vulnerable households based on their budget constraint and the composition of their financial portfolio. Then, we calculate the impact of the predicted trends of macroeconomic variables on the indicator in order to monitor its evolution in the short term (2015–2017). The empirical analysis is based on the Survey of Household Income and Wealth of the Bank of Italy and on a set of macroeconomic forecasts. Our findings suggest that the macroeconomic scenario for the period 2015–2017 implies a progressive reduction in the percentage of vulnerable households for the full extent of the projection.     

Heterogeneous technology and panel data: The case of the agricultural production function

Economic growth involves reallocating resources from traditional to new techniques of production, creating new relationships between particular resources and productivity. The paper analyzes the implications of this process on the estimation of agricultural production functions using a panel of countries. The data includes a measure of capital in agriculture absent from most studies. We employ a heterogeneous technology framework where implemented technology is chosen jointly with inputs to interpret information obtained in the empirical analysis of panel data. In this framework, estimates depend upon the economic environment, which is represented by state variables. It turns out that the old problem of identifying the production function cannot be resolved through the use of instrumental variables, but can be resolved using the allocation error. The paper discusses the scope for replacing country and time effects by observed state variables. The empirical results differ from those reported in the literature for cross-country studies, largely in augmenting the elasticities of capital and land and reducing those of fertilizer and labor. The evaluation of the marginal value productivity accounts for the flow of capital and fertilizer to agriculture and the flow of labor to other sectors, thereby contributing to overall economic growth.     

An Exploration of the Role Duality Experienced by HR Professionals as Both Implementers and Recipients of HR Practices: Evidence from the Indian Railways

This study provides an innovative perspective on empirically assessing HR by focusing on the duality of HR professionals’ experiences as both implementers and recipients or internal customers of HR practices given that they are also employees of the organization. We hypothesize that HR professionals experience HR practices more favorably from an implementer perspective as compared to an internal customer perspective. These differences in experiences are likely to be influenced by HR professionals’ hierarchical position in the HR department. Our analyses of 1,271 HR professionals employed by Indian Railways revealed a number of differences between the two types of experience. Some practices (recruitment and selection, training, and employee welfare) were viewed more negatively from the implementer perspective, whereas others (compensation, benefits, and employment relations) were rated more negatively from the internal customer perspective. Those holding more senior HR positions reported more positive experiences of training and employment relations from an internal customer perspective. Overall our contributions draw on the attribution theory and concepts of intraorganizational power and voice, and have implications concerning the effectiveness of HR practices. © 2015 Wiley Periodicals, Inc.
