This article examines whether financial sector development has ‘caused’ economic growth and investment in Ghana between 1970 and 2007. As a proxy for financial sector development we use credit to private sector as per cent of GDP, bank liquid reserve – asset ratio and liquid liability as a...

We estimate a Vector Error Correction Model to explore the long run and short run linkages between the world crude oil price and economic activity in Ghana for the period 1970:1 to 2006:4. The results point out that there is a long run relationship between the variables under consideration. We...

In this note, we develop a search-based monetary growth model to analyze the growth and welfare effects of inflation. We introduce endogenous growth via capital externality into a two-sector search model and compare the effects of inflation to those from a standard cash-in-advance (CIA) growth...

A special characteristic of the patent system is that it features multiple patent-policy levers that can be employed by policymakers. In this study, we develop a quality-ladder model to analyze the optimal mix of patent instruments. Specifically, we consider (a) patent breadth and (b) the...

This paper provides a survey on studies that analyze the macroeconomic effects of intellectual property rights (IPR). The first part of this paper introduces different patent-policy instruments and reviews their effects on R&D and economic growth. This part also discusses the distortionary...

This study examines the role of macroeconomic variables on stock prices movement in Ghana. We use the Databank stock index to represent Ghana stock market and (a) inward foreign direct investments, (b) the treasury bill rate (as a measure of interest rates), (c) the consumer price index (as a...

How do intellectual property rights that determine the market power of firms influence the effects of monetary policy on economic growth and social welfare? To analyze this question, we develop a monetary R&D-based growth model with elastic labor supply. We find that monetary expansion reduces...

This study develops a Schumpeterian growth model to analyze the effects of different patent instruments on innovation. We first analyze patent breadth that captures the traditional positive effect of patent rights on innovation. Then, we consider a profit-division rule between entrants and...

This study develops an R&D-based growth model with basic and applied research to analyze the growth and welfare effects of two patent instruments (a) the patentability of basic R&D and (b) the division of profi�t between basic and applied researchers. We �find that for the purpose of...

This study develops an R&D-based growth model with vertical and horizontal innovation to shed some light on the current debate on whether patent protection stimulates or stifles innovation. We analyze the effects of patent protection in the form of blocking patents. We show that patent...
