Premium and reinsurance control of an ordinary insurance system with liabilities driven by a fractional Brownian motion

This paper investigates the problem of premium and reinsurance control of an ordinary insurance system when liabilities are driven by a fractional Brownian motion. The reserve equation is considered using two alternative routes: the first with no reinsurance option, and the second with some controllable proportional reinsurance coverage. Recent results from the theory of fractional linear-quadratic control (fractional calculus) are discussed, partially extended and utilized to derive compact analytical formulae for the optimal functionals of the safety loading (consequently for the respective premium rate), and the volume of the retained risk (or equivalently, for the proportion of the reinsurance coverage).     

Absorptive capacity, innovation, and financial performance

This study here examines the role of absorptive capacity as both a mechanism to identify and translate external knowledge inflows into tangible benefits, as well as a means of achieving superior innovation and time-lagged financial performance. Using path analysis in a sample of 461 Greek enterprises participating in the third Community Innovation Survey, this study demonstrates that external knowledge inflows are directly related to absorptive capacity and indirectly related to innovation. Absorptive capacity contributes, directly and indirectly, to innovation and financial performance but in different time spans. This study, therefore, contributes to the understanding of absorptive capacity's antecedents and outcomes by providing empirical evidence of longitudinal form that offers important research and practical implications.     

The Technology Fair: a project-based learning approach for enhancing problem solving skills and interest in design and technology education

This paper presents an innovative way in which university education can help pre-service teachers become better problem-solvers. The central idea is to use the “Technology Fair” as a means for promoting pre-service teachers pedagogical content knowledge about technological problem solving skills. This innovation is supported with results from a study carried out in autumn 2004. The purpose of the study was to investigate the influence of a procedure of working with primary school children to complete and present a technology fair project, on the educational value and meanings attached to problem solving skills by pre-service teachers. Pre-tests, mid-test and post-tests were administered to the pre-service teachers before, during, and after the preparation of the technology fair, respectively. A number of pre-service teachers were selected and interviewed after the completion of the technology fair. Data were also collected from reflective diaries kept by the pre-service teachers during the preparation phase of the technology fair. Analysis of the results indicates that the technology fair contributes to the development of positive values and attitudes in technology education and has a significant influence on improving pre-service teachers understanding and application of problem solving strategies within the domain of technology.     

OPTIMAL MONETARY POLICY AND ASSET PRICE MISALIGNMENTS

This paper analyses the relationship between monetary policy and asset prices in the context of optimal policy rules. The transmission mechanism is represented by a linearized rational expectations model augmented for the effect of asset prices on aggregate demand. Stabilization objectives are represented by a discounted quadratic loss function penalizing inflation and output gap volatility. Asset prices are allowed to deviate from their intrinsic value due to momentum trading. We find that in the presence of wealth effects and inefficient markets, asset price misalignments from their fundamentals should be included in the optimal interest rate reaction function.     

The investment development path in space

Although spatial hypotheses are not new in the FDI literature, their examination in the dynamic context of the ‘investment development path’ (IDP) provides some new insights. In this paper, we examine proximity to markets at different stages of the IDP as a determinant of a country’s own foreign direct investment (FDI) pattern. Our main contribution lies in the empirical estimation of the importance of spatial determinants for the emergence of inward and outward FDI. Our results support that distance to countries at higher stages up the IDP which are better integrated into the world FDI network, has a negative effect on the probability of transition from any stage of the IDP to the next. The magnitude of the impact is generally increasing in the stage of the surrounding markets.     

Managing mutual funds or managing expense ratios? Evidence from the Greek fund industry

This study examines the expense ratio policy of Greek equity funds operating in a small emerging market with an oligopolistic, bank-dominated financial system. Constructing a unique dataset of non-publicly available expense ratios charged by these funds, we examine the impact these expenses have on funds’ performance and flows. The main conclusion is that funds’ performance is negatively related to their expenses, while investors’ flows are not directly affected by expenses. Furthermore, the funds affiliated with one of the three dominant domestic banking groups achieve higher performance and attract higher net flows in comparison to their competitors.     

Is it all about money? An examination of the motives behind moonlighting

Multiple-job holding is an important labour market phenomenon. In this article, we examine individuals’ motives for multiple-job holding. Specifically, we estimate an empirical model of the motivation for moonlighting assuming that individuals hold a second job for either financial or for nonpecuniary motives. Our results contribute to a better understanding of multiple-job holding. We find that multiple-job holding is used by individuals as a way to deal with the financial difficulties or the increased financial commitments in their household. Individuals are more likely to moonlight for money in the early stages of their adult life. Finally, individuals with more labour market experience are more likely to moonlight for pecuniary than nonpecuniary reasons.     

Stock market reaction to fed funds rate surprises: State dependence and the financial crisis

This paper examines the response of US stock returns to Federal Funds rate (FFR) surprises between 1989 and 2012, focusing on the impact of the recent financial crisis. We find that outside the crisis period, stock prices increased as a response to unexpected FFR cuts. State dependence is identified with stocks exhibiting larger increases when interest rate easing coincided with recessions, bear markets, and tightening credit conditions. However, an important structural shift occurred during the crisis, changing the stocks’ response to FFR shocks and the nature of state dependence. Throughout the crisis period, stocks did not react positively to unexpected FFR cuts, which were interpreted as signals of worsening future economic conditions. This triggered a rebalancing of investment portfolios away from falling equities and towards safe-haven assets. Our results highlight the severity of the crisis and the ineffectiveness of conventional monetary policy close to the zero lower bound.     

FORECASTING US INFLATION USING DYNAMIC GENERAL‐TO‐SPECIFIC MODEL SELECTION

We forecast US inflation using a standard set of macroeconomic predictors and a dynamic model selection and averaging methodology that allows the forecasting model to change over time. Pseudo out‐of‐sample forecasts are generated from models identified from a multipath general‐to‐specific algorithm that is applied dynamically using rolling regressions. Our results indicate that the inflation forecasts that we obtain employing a short rolling window substantially outperform those from a well‐established univariate benchmark, and contrary to previous evidence, are considerably robust to alternative forecast periods.
