Endogenous Growth Models and Stock Market Development: Evidence from Four Countries

This paper re‐examines the relationship between stock market development and economic growth. It provides a theoretical basis for establishing the channel through which stock markets affect economic growth in the long run. It examines the hypothesis of endogenous growth models that financial development causes higher growth through its influence on the level of investment and its productivity. The empirical part of this study exploits techniques recently developed to test for causality in VARs. The evidence obtained from a sample of four countries suggests that investment productivity is the channel through which stock market development enhances the growth rate in the long run.     

Interest rate convergence, capital controls, risk premia and foreign exchange market efficiency in the EMS

This paper examines interest rate convergence between Germany and the other EMS countries. We argue that earlier tests of convergence based on cointegration are not informative, because cointegration only implies that a linear combination of interest rates is stationary. We show that a conclusive judgment about convergence can be made if interest rate differentials exhibit a trend towards zero during the period when convergence occurred, and if the cointegrating vector has unit coefficients. We then establish that convergence has taken place in the “hard” EMS period. We also attempt to identify the sources of nonstationarities in interest differentials by examining the existence of stochastic or deterministic trends in the expected rate of depreciation and in the risk premium. Finally, the possibility of market inefficiencies is discussed.     

Using a dual system of reasoning in small businesses: Entrepreneurial decisions and subjective risk intelligence

This study aims at introducing subjective risk intelligence (SRI) in the context of small businesses to analyze how both rationality and intuition may influence the entrepreneurial decision-making process, particularly in affecting firms’ financial equilibrium.

SRI aggregates four dimensions: two positive attitudes (imaginative capability and problem-solving self-efficacy) and two detrimental ones (emotional stress vulnerability and negative attitude towards uncertainty). In particular, we argue that imaginative capability and emotional stress vulnerability refer to Kahneman’s System 1 (the intuitive), while problem-solving self-efficacy and negative attitude towards uncertainty appertain to System 2 (the rational).

We conducted an empirical investigation collecting data from an ad hoc survey administered to owners and managers of small businesses and their balance sheets over 2013–2017. After testing the proposed constructs’ reliability, we tested the influence that both Systems 1 and 2 have on SMEs’ financial structure through a pooled OLS regression estimator.

Results show that the intuitive and the rational components of risk intelligence affect entrepreneurs’ decision-making differently. The rational component seems to stimulate the entrepreneurial orientation to risk tolerance. The intuitive component limits the entrepreneurial propensity to take financial risks due to the desire for stability attached to this cognitive process. Accordingly, we highlight the importance of enhancing a balance between the two systems of thinking. Practical implications suggest that entrepreneurs with a dominant attitude towards problem-solving self-efficacy, or a positive attitude towards uncertainty, should invest in developing imaginative capabilities or emotional control, and vice versa.

     

Testing for Seasonal Fractional Roots in German Real Output

Abstract. This paper examines the seasonal structure of German real GNP per capita by using a version of Robinson's (1994) tests which is suitable in the context of seasonality. This method has several advantages over alternative approaches when testing for seasonal unit roots. First, unlike standard tests, which are nested in AR alternatives, it is embedded in fractional alternatives. Second, it allows testing at the zero frequency and at each of the seasonal frequencies separately. Third, it makes it possible to test for different orders of integration at each of the frequencies simultaneously. The empirical analysis suggests that the real output series may have a unit root at the zero frequency, and fractional rather than unit roots at the seasonal ones. This is in contrast to the findings reported by Lutkepohl et al. (1999) in their study on German money demand, and shows the importance of modelling the seasonal features of the data in alternative ways.
