Health Insurance, Liquidity and Growth

Within the context of an endogenous growth model, it is shown that in the presence of health risks which influence household income, the introduction of a private insurance company increases the long-term economic growth rate. The introduction of such an institution has two effects on savings: a level effect and a composition effect. Although the presence of this risk-reducing institution induces a decrease in the level of total savings, as suggested in earlier papers, the rate of illiquid savings, which contribute to growth, increases.

Option overlay strategies

Option overlays on a rebalanced portfolio are designed. Inputs to the design problem are the physical and risk neutral probabilities at the option maturity. They are estimated from time series and option data, respectively. The objective for the design is the bid price of a two price economy modelled as a distorted expectation. The design is monotone increasing in the underlier with a delta constraint. The option positioning is implemented on the S&P 500 index, supposedly rebalanced every 21 days with option positions taken 10 days prior to a rebalance date with a maturity near two months. Option overlays are seen to raise performance measures and reduce drawdowns.     

Knowledge spillovers and high-impact growth: Comparing local and foreign firms in the UK

This paper is concerned with entrepreneurial high-impact firms, which are firms that generate ‘both’ disproportionate levels of employment and sales growth, and have high levels of innovative activity. It investigates differences in the influence of knowledge spillovers on high-impact growth between foreign and local firms in the UK. The study is based on an analysis of data from UK Innovation Scoreboard on 865 firms, which were divided into ‘high-impact firms’ (defined as those achieving positive growth in both sales and employment) and low-impact firms (negative or no growth in sales or employment). More precisely, the paper investigates the influence of knowledge spillovers on high-impact growth of foreign and local firms, from regional, sectoral and firm size perspectives. The findings suggest that (1) firms’ access to regional knowledge spillovers (from businesses and higher education institutions) is more significantly associated with high-impact growth of local firms in comparison to foreign firms; (2) because knowledge spillovers are more likely to occur in high-tech sectors (compared to low-tech sectors), firms in high-tech sectors are more associated with high-impact growth. Nonetheless, the relationship is stronger for local firms compared to foreign firms; (3) because small firms have greater need for knowledge spillovers (relative to large firms), there is a negative relationship between firm size and high-impact growth, but the negative relationship is greater for UK firms in comparison to foreign firms. Implications are drawn for policy and research.     

Dynamic Effects in Senegal of the Regional Trade Agreement Among UEMOA Countries

In an international setting characterized by a proliferation of regional trade agreements, seven countries of the West African Economic and Monetary Union (UEMOA) have created a customs union. The reform raises concerns in some countries, like Senegal, where government is dependent on tariff revenues. The author builds an intertemporal general equilibrium model to analyze the dynamic effects of the reform. Simulation results highlight the desirability for Senegal to pursue regional economic integration along with an outward-looking strategy. The reform is welfare-improving and expansionary with some sectoral diversity. In the long run, government and foreign debts increase.     

Foreign direct investment and entrepreneurship: Does the role of institutions matter?

Development economics, international business, and entrepreneurship literature suggest that foreign direct investment (FDI) has significant positive spillover effects for entrepreneurial activities of host economies. However, the findings of past research are mixed, and they do not always confirm this suggestion. We argue that the reason for conflicting findings may be because of an incomplete understanding of the factors that influence the FDI-entrepreneurship nexus in different contexts. Previous studies have carried out only limited exploration of the contingencies in the FDI and domestic entrepreneurship relationship that may depend on the host country’s institutional capacity. We argue that not all countries can reap the rewards from FDI equally. Rather, we hypothesize that countries need to have a sufficient degree of institutional capacity relevant to specific conditions and appropriate threshold levels to successfully capture the positive spillover effects of FDI on domestic entrepreneurship. Utilizing panel data from 2006 to 2016 for 97 emerging markets, developing and developed countries (at different income levels), and a System Generalized Method of Moments (SGMM) estimator that controls for instrument proliferation in dealing with endogeneity problems, we test this hypothesis. We find that FDI has a negative (crowding-out) effect on domestic entrepreneurship at below-threshold levels of institutional capacity, and a positive (crowding-in) effect at above-threshold levels of institutional capacity. The crowding-out effect diminishes as the institutional capacity changes or improves to meet mutating economic environment conditions. Our findings are robust across a wide range of aggregate and disaggregate measures of different types of institutions and alternative empirical strategies.
