Employees' concerns about change and commitment to change among Italian organizations: the moderating role of innovative work behavior

Despite being regarded as a critical psychological process influencing the effectiveness of change initiatives, concerns about change have not received empirical attention in the organizational change literature. The present study addresses this issue by examining the relationships among employees' concerns about change (conceptualized as including concerns about the contents and benefits of change, and concerns about mastering the change), commitment to change and innovative work behavior. First, in a hospital undergoing a major administrative change (N = 435), concerns about change were generally found to be negatively related to affective and normative commitment to change and positively related to continuance commitment to change. These results were replicated in a chemical and pharmaceutical company undergoing a technological change (N = 113), except that concerns about change were unrelated to normative commitment to change. In addition, employees' innovative work behavior moderated the relationship of concerns about change to affective commitment to change such that the relationship was negative when innovative behavior was low but nonsignificant when innovative behavior was high. This study provides scholars and practitioners with a theoretically and empirically grounded framework for assessing employees' concerns about change, and moves research a step forward into identifying the behaviors that organizations should support to counteract this psychological threat.     

Model risk in credit risk

We provide sharp analytical upper and lower bounds for value‐at‐risk (VaR) and sharp bounds for expected shortfall (ES) of portfolios of any dimension subject to default risk. To do so, the main methodological contribution of the paper consists in analytically finding the convex hull generators for the class of exchangeable Bernoulli variables with given mean and for the class of exchangeable Bernoulli variables with given mean and correlation in any dimension. Using these analytical results, we first describe all possible dependence structures for default, in the class of finite sequences of exchangeable Bernoulli random variables. We then measure how model risk affects VaR and ES.     

The supply of education quality in a spatial model with asymmetric moving costs

The paper analyses the characteristics of the supply of higher education in different geographical macroareas using a strategic interaction framework. It focuses on universities operating in centralised funding system that autonomously set the quality of education showing that in equilibrium it is inversely related to students’ moving costs across areas. We show that in the presence of asymmetric information about workers’ ability and asymmetric costs of moving, the only PBE consistent with forward induction involves that only high ability workers acquire education and the quality of education is lower in macroareas where the moving costs are higher. Our model predicts that in economies with centralised university funding, educational policies must be regulated according to the specific socioeconomic characteristics of the area. Direct subsidies to universities may be ineffective in improving the quality of education in the less developed areas. When regional disparities are not too big, efficiency gains may be obtained by reducing moving costs.     

Single and joint default in a structural model with purely discontinuous asset prices

Structural models of credit risk are known to present both vanishing spreads at very short maturities and a poor spread fit over longer maturities. The former shortcoming, which is due to the diffusive behaviour assumed for asset values, can be circumvented by considering discontinuous asset prices. In this paper the authors resort to a pure jump process of the Variance-Gamma type. First the authors calibrate the corresponding Merton type structural model to single-name data for the DJ CDX.NA.IG and CDX.NA.HY components. By so doing, they show that it also circumvents the diffusive structural models difficulties over longer horizons. Particularly, it corrects for the underprediction of low-risk spreads and the overprediction of high-risk ones. Then the authors extend the model to joint default, resorting to a recent formulation of the VG multivariate model and without superimposing a copula choice. They fit default correlation for a sample of CDX.NA names, using equity correlation. The main advantage of our joint model, with respect to the existing non-diffusive ones, is that it allows full calibration without the equicorrelation assumption, but still in a parsimonious way. As an example of the default assessments which the calibrated model can provide, the authors price an FtD swap.     

Survival of the fittest: The impact of eco‐certification and reputation on firm performance

Owing to the increased trend for organic products and the concept of sustainable development, firms must invest in valuable and unique resources to achieve long‐term success and gain competitive advantages. Building on insights from the resource‐based view and natural‐resource‐based view of the firm, the study focuses on the contribution of corporate reputation and eco‐certification as intangible influences on corporate performance. Duration analysis is applied on a sample of 1,572 German wineries over the period 1994 to 2017. The results indicate that individual reputation and eco‐certification have a statistically significant and positively impact on corporate performance, whereas there is no clear evidence of this relationship for collective reputation. In addition, especially those firms with high individual reputation benefit most from eco‐certification. These results are robust across different parametric and semiparametric model estimations.     

The distributive impact of terms of trade shocks: The case of the oil price changes in Russia

The halving of oil prices, during a short period between 2014 and 2015, has generated major terms of trade losses for oil exporting countries. This terms of trade shock has economy‐wide effects and significant distributive impacts. This paper, using a macro‐micro simulation model, describes and quantifies the channels of transmission from the drop of oil prices, to changes in welfare distribution at the household level for the case of the Russian Federation. The oil price reduction generates a reverse Dutch disease impacting sectoral employment, factor returns and consumption prices. It causes a contraction of employment and wages in more skill‐intensive (non‐tradable) sectors, and a reduction in consumption prices that is more pronounced for non‐food than for food goods. When these shifts are mapped to changes in incomes at the micro level, all households are affected. Poverty rates increase by 1 to 4 percentage points, depending on the poverty line used. At the US$ 10 a day threshold, 4.1 million additional people fall into poverty. Along the consumption distribution, richer people are affected more than those in the bottom 40%. However, this minor progressive impact may be reversed due to increases in unemployment and cuts in social programmes.     

A test for the too-big-to-fail hypothesis for European banks during the financial crisis

Motivated by the theoretical prediction of the opportunistic behaviour of large banks that face expected public intervention, we test a full and a partial form of the too-big-to-fail (TBTF) hypothesis. The full form of the hypothesis implies the increase in the risk undertakings and profitability of banks that exceed a certain dimension; the partial form of the hypothesis implies only an augmented risk appetite of large banks compared to their smaller counterparts. The examined area is the European banking industry, whose behaviour is observed over the first wave of the present financial crisis (2007/09). The estimation of a quadratic fit that links change in a bank’s credit risk profile and profitability retention rates with a bank’s size suggests the existence of a partial form of the TBTF hypothesis. However, a more precise, local rolling windows estimation of the size sensitivities reveals that large banks – those whose liabilities exceed approximately 2% of the country of origin’s GDP (15% of our sample) – show an increase in credit risk profile and a superior capability of retaining higher ROA scores, vis-à-vis their smaller counterparts. With the caveats of our investigation, we interpret these results as evidence of a full form of the TBTF hypothesis.     

The diffusion of a new telecommunication service : Network constraints and service quality in a dynamic interpretative model

In this paper, a discrete time model for the adoption of a new telecommunication service is proposed. We analyze the interaction of three sets of agents involved in the process: users, information providers, and network providers. We consider the effects of the network constraint and of the expectations of the users and suppliers.
