The control variables included are; capital, labour, direct investment, GDP per capita, the number of export products and secondary...
Food Prices and Economic Well-Being in Sub-Saharan Africa
August 2016
Over the years, Sub-Saharan Africa has been one of the regions worst hit with the deleterious effects of food insecurity owing to the soaring prices of food items. Therefore, this paper examines the effects of rising food prices on economic well-being in 31 Sub-Sahara African countries from 2001-2012 using panel regressions. Findings from the study reveal that both contemporaneous and the initially prevailing food...

Do Economic Policy Decisions affect Stock Market Development in Ghana?
August 2016
The Efficient Market Hypothesis proposes that macroeconomic policy actions do not influence stock market development but the Tobin’s q theory argues otherwise. This paper uses the autoregressive distributed lag (ARDL) technique to investigate the impact of macroeconomic policy on the development of the Ghana Stock Exchange for the period 1991-2011. The paper finds government revenue and exchange rate reduce stock...
TESTING THE VALIDITY OF WAGNER’S LAW IN THE NAMIBIAN CONTEXT: A TODA-YAMAMOTO (TY) GRANGER CAUSALITY APPROACH, 1991-2013

Regressed-income sources...
The Determinants of Inflation in Botswana and Bank of Botswana’s Medium-Term Objective Range
December 2013
This study is motivated by the high and unstable episodes of inflation in Botswana over the last 20 years or so. This is despite the Bank of Botswana’s (BOB) concerted effort to keep inflation at its minimum and stable over time. More specifically, it has been attempting to bring down and keep inflation within the medium-term objective range of 3 to 6percent. The objectives of this study are, therefore, to: (a)...

Welfare Effects of Higher Energy and Food Prices in Botswana: A SAM Price Multiplier Analysis
December 2013
Using a social accounting matrix (SAM) multiplier framework, the paper examines the welfare effects of higher prices of internationally traded energy and food commodities on economic sectors in Botswana.

The findings indicate that the effects of these shocks are heavily concentrated on very few...
Is it true that Good Institutions Alleviate the Resource Curse? A Re- assessment of Existing OLS Cross Country Evidence
December 2012
The paper tests the hypothesis that the effect of resources on growth is conditional on the quality of institutions, by further building on Mehlum, Moene, and Torvik’s (2006b) influential work. Advances are made by re-testing the hypothesis, using: (a) a dataset of up to 53 countries over the period 1984-2003; and (b) a resource abundance indicator that focuses on non-renewable resources alone rather than the ones...
Measuring the second economy in Zimbabwe
December 2012
The second economy in Zimbabwe have grown from less than 10% of official GDP at independence in 1980 to an all-time higher share of 70 percent in 2008 before subsiding to a still higher percentage share of 52% by end of 2009. The existence of such a sizeable sector of unrecorded domestic and international economic transactions has several implications relevant for policy. First, it suggests that cconsiderable efforts...

Monetary Policy Shocks and Stock Returns Reactions: Evidence from Botswana
December 2012
This paper applies standard vector autoregressions (VAR) technique to quarterly data for Botswana for the period 1993-2010 to investigate the impact of monetary policy shocks on stock returns.

The importance of the soundness and effectiveness of governance in attaining increased investment and sustained economic growth cannot be overemphasized. The specific objectives were to estimate the short-run dynamics as well as the error-correction mechanism of...
The Impact of Increased Efficiency in the Transport Sectors? Energy Use: A Computable General Equilibrium Analysis for the Botswana Economy
December 2011
Energy efficiency is viewed as a tool for achieving both sustainable development and environmental sustainability in Botswana and world-wide. This is premised on the standard wisdom that energy-augmenting technical progress reduces aggregate energy consumption. In the energy economics literature, there is disagreement as to whether the beneficial effect of energy efficiency stimulus on energy consumption is partially or...

CREDIT RATIONING AND SME DEVELOPMENT IN BOTSWANA: IMPLICATIONS FOR ECONOMIC DIVERSIFICATION
December 2011
Economic diversification is a key policy goal for the Government of Botswana. SMEs offer a feasible option towards the actualisation of this goal. The expansion of SMEs in Botswana however is constrained by lack of access to bank credit. This constrained access to credit is argued in the literature to be due to the credit rationing behaviour of banks emanating from asymmetric information in credit markets. Constrained...
Are Devaluations Contractionary in Small Import-dependent Economies? Evidence from Botswana
December 2011
This study tests the contractionary devaluation hypothesis in the context of a small open import-dependent economy. Using an error-correction model that controls for monetary policy, fiscal policy, base country output and interest rates, the study finds that currency devaluations are contractionary in the long run and expansionary in the short-run. Other results are that increases in government consumption expenditure...
