Bilateral Trade Performance in West Africa: A Gravity Model Estimation

This study provides empirical insights on the functioning of regional trade agreements within the Economic Community of West African States (ECOWAS) by identifying bilateral trade barriers that affect the extent of trade flows among member countries. Also, it highlights some trade barrier indicators that are rarely covered in extant studies, such as the multilateral resistance term, the extent of trade complementarity, and the presence of economic integration agreements among ECOWAS member countries. We then provide augmented gravity model estimation on the determinants of bilateral trade in the region. We find, among other things, that trade complementarity had a positive and significant effect on bilateral trade within the sub‐region region. Other important determinants of intra‐regional trade include multilateral trade resistance and economic integration agreements — meaning that countries with some kind of agreement like the West African Economic and Monetary Union (WAEMU) tend to trade more among themselves than other member countries.     

LONG‐RUN DETERMINANTS OF SAVINGS RATES IN WAEMU COUNTRIES: AN EMPIRICAL ASSESSMENT FROM ARDL BOUNDS TESTING APPROACH

In this paper, we examine the long‐run determinants of savings rates for seven member countries of the West African Economic and Monetary Union over the period 1970–2006. We use the bounds testing approach to cointegration developed by Pesaran et al. This methodology has several advantages with respect to other cointegration tests. The long‐run determinants of savings rate vary across countries. Results reveal that the financial liberalization process undertaken at the end of 1989 and the existing monetary policy have not been effective to increase the domestic savings rates within the area.     

Banks,Microfinance Institutions and Economic Growth in the West African Economic and Monetary Union

Abstract: This paper aims to investigate the complementary relationship between commercial banks and microfinance institutions in the West African Economic and Monetary Union (WAEMU) as a means to sustain economic growth. Using panel data on seven countries from 1999 to 2005 with the Feasible Generalized Least Squares and the AR(1) disturbances, the study indicates that the banking and microfinance sectors are prone to operating individually, and that banks benefit from microfinance activities. A joint effort of both sectors in facing credit allocation appears to be very significant over the single action of microfinance institutions. The study, therefore, suggests a joint or complementary approach through savings management to face the challenge of the economic growth in the Union.     

Financial dualism: An analysis of the effects of informal finance on formal finance in West African Economic and Monetary Union (WAEMU) countries

This paper analyzes the effects of informal finance on formal finance in West African Economic and Monetary Union (WAEMU) countries. To this end, it uses a Probit model with a binary endogenous regressor and data from the Global Findex database, 2021. The findings indicate that having already saved informally positively affects the behavior of individuals to save formally. They also indicate that informal financial credit positively affects formal financial credits in the WAEMU. These findings indicate that formal finance is complementary to informal finance in the WAEMU. On the other hand, the findings show that labour force participation, mobile banking use and online banking use increase the likelihood of use of formal and informal services in the WAEMU. This paper suggests that formal financial institutions (mainly banks and microfinance institutions) should strengthen their collaboration with actors (money keepers, itinerant bankers, tontines systems) involved in the provision of informal financial services to populations in order to improve formal financial intermediation in the WAEMU.     

Money demand in the West African economic and monetary union - the problems of aggregation

Regional monetary integration, financial liberalisation andthe adoption of indirect policy instruments continue to changethe conditions for monetary policy in the West African Economicand Monetary Union (WAEMU). While the identification of a stablemoney demand relationship has become a crucial element for monetarypolicy, differences in economic behaviour between Côted'Ivoire and the remaining countries may induce instabilityat the aggregate level. This paper analyses the demand for moneyfor the entire WAEMU, the six smaller member countries, andCôte d'Ivoire. A stable aggregate money demand functionis identified and interpreted in light of the results for thesub-regional estimations.     

欧元危机的逻辑

本次危机的根源是欧元区外围国家的过度举债和核心国家的有借必应。欧洲货币联盟的治理框架为成员国之间的过度信贷开了方便之门。为了研判欧元区的前景,将外围成员国分为四类:有清偿能力和无清偿能力的国家,具有纠正宏观失衡意愿和不具有纠正失衡意愿的国家。经过调整,西班牙和爱尔兰的债务状况已经好转;新任保守党政府或将帮助葡萄牙扭转颓势;希腊退出欧元区几成定局;技术派政府"新政"或为意大利迎来转机;法国对欧元区的态度或因大选发生转变。     

A single currency for the Economic Community of West Africa? An economic assessment

This paper assesses the economic support for the creation of an Economic Community of West African States (ECOWAS) monetary union encompassing all its 15 members, an objective that was set more than 30 years ago. In line with previous empirical research, our conclusion is that the adoption of a common currency by the whole region is not recommended. This work takes a step forward and assesses alternative ways to reduce the current number of currencies in circulation in the Community. Based on our results, we suggest (i) the merging of the currencies of Guinea, Liberia and Sierra Leone into a single currency and (ii) the Gambia to join the West African Economic and Monetary Union (WAEMU).     

Analysis of tax effort in WAEMU: How important are institutional/administrative reforms?

This paper examines, in depth, the hypotheses explaining the tax effort of seven West African Economic and Monetary Union (WAEMU) countries over the period 1996–2018. The studies of Karakaplan and Kutlu were applied to the stochastic tax frontier model. This provides a new method for analyzing tax effort that solves potential endogeneity problems, especially those of income. This study confirms the positive impact of income, trade openness, urbanization, government capital spending and anticorruption on tax revenue mobilization, while the size of the agricultural sector has a negative impact on tax revenue. On the other hand, reforms of tax institutions have no effect on tax effort. The average tax revenue of the countries of the WAEMU is 11.34 and the average tax effort is estimated at 0.7901 over the period 1996–2018. Thus, these countries could achieve a tax revenue to GDP ratio of 13.72% if they fully exploit their potential.     

The International Reserves Issue in the EMU

This paper examines the effects of the Economic and Monetary Union on demand for foreign reserves. The traditional theory on demand for international reserves assigns a pivotal role to imports. However, in a currency union part of imports are settled in the common currency, leaving no incentive for keeping foreign reserves. Moreover, the pooling of the demand for reserves in the currency union and an increasing role of a currency as an international reserve currency may also influence, among other things, the union demand for reserves. Based on estimated demand functions for reserves it is shown that the Economic and Monetary Union has reduced the demand for reserves substantially. It is argued that an enlargement with new member countries of the European Union will result in further savings of reserves. A simple calculation at the end of the paper illustrates the welfare gain associated with the reduced need of reserves in the Economic and Monetary Union.     

The Stability and Growth Pact: The appropriate fiscal framework for EMU

Developments in fiscal policies since the start of Economic and Monetary Union have time and again raised the question of whether the Stability and Growth Pact (SGP) provides an appropriate framework for fiscal policy coordination. Critics have argued that the SGP, in particular the set of rules specifying the application of the 3% deficit reference value of the Maastricht Treaty, is too rigid as it could force countries to restrain fiscal policies in difficult times and exacerbate cyclical volatility. Moreover, the SGP has been accused of inhibiting growth by limiting useful public expenditure (e.g. on investment). Supporters argue that the SGP provides a constructive, and indeed indispensable, framework for fiscal policies in Monetary Union. It is credited with securing stable and sustainable public finances within adequate bounds of flexibility. In the current dire state of public finances in many Member States and at the euro area level, this debate has reached a new peak.I would like to thank Philipp C. Rother for his valuable contributions.     

Macroeconomic adjustment programmes in the euro area: an overall assessment

Since the start of EMU (Economic and Monetary Union), the euro area, and more broadly the global economy, experienced an unprecedented credit boom. The expansion of credit was particularly strong in Greece, Ireland, Portugal and Cyprus and all of them subsequently needed official financial support. In each of the four programmes, financial assistance has been provided and promised against the commitment of each country to fulfil certain economic policy conditions contained in the macroeconomic adjustment programme. In general, a macroeconomic adjustment is a process driven by policies but also by changes in private spending behaviour (consumption, imports, investment) and improvement in competitiveness that countries are required to undertake after a large shock. In the case of the four countries, the shock emerged as a consequence of an excessive accumulation of imbalances in different parts of the economy: in the public sector in Greece, in the housing and banking sectors in Ireland, external imbalances in Portugal and in the banking sector in Cyprus. The paper looks at the feasibility of the fiscal adjustment comparing the macroeconomic conditions in the four countries and emphasising the role of the fiscal multipliers in the process. It also assesses the fall in the output in a comparative framework, stressing the role played by the different components of demand either in amplifying the effect of the fiscal consolidation or in offsetting it. In addition, it considers formulation of the programmes as well as their implementation with most attention devoted to reforms aiming at improving competitiveness, growth and employment in the framework of a cross-country approach.     

Ease of doing business and investment among West African countries

This study assessed the link between ease of doing business (EBD) and investment among 11 selected countries in West Africa covering 2006–2020. The study used the fixed-effects estimator, the random-effects estimator, the augmented mean-group method, and the Half-Panel Jackknife Wald-type test. The study found a bidirectional relationship between the EBD and foreign direct investment (FDI) and a unidirectional relationship running from EBD to domestic investment. The findings further revealed that the EBD and national income have a strong influence in determining the level of domestic investment and FDI inflows, and that some indicators of EBD, such as the procedure for starting a business, access to credit facilities, tax, and security threats, discourage domestic investment and FDI inflows, in contrast to the influence of obtaining electricity and national income on investment. The study suggests that West African governments reduce taxes, ease the procedures and costs of starting a business and dealing with construction permits, and increase the availability of credit facilities at lower interest rates to promote investment in the region.     

Social protection and regional convergence in a European Monetary Union

This paper addresses convergence in social protection and GDP in a European Economic and Monetary Union. We evaluate the impact of recently proposed EC social minimum requirements on regional convergence within the EC. Subsequently, we analyze a system of differentiated social norms as a means of raising social protection in countries with lower social standards.     

Effects of financial inclusion on tax revenue mobilization: Evidence from WAEMU countries

Financial inclusion remains at the heart of governments concerns. By creating favorable conditions for access to a diversified range of adapted financial products and services at affordable costs for the populations, financial inclusion generates important opportunities that could lead to increased tax revenue mobilization. This paper analyzes the effects of financial inclusion on tax revenue mobilization, using panel data from West African Economic and Monetary Union (WAEMU) countries over the period 2006–2019. The findings suggest that financial inclusion positively and significantly influences government's tax revenue. Moreover, by looking at the effects of disaggregated financial inclusion dimensions (access, use, and affordability) on various components of tax revenue, we find that the estimated coefficients on the subcomponents of financial inclusion are statistically significant. Results also indicate that the magnitude of effect of financial inclusion is higher on indirect taxes compared to direct tax revenues. This research recommends that policy-makers should prioritize financial inclusion in their policies and development agenda through National Financial Inclusion Strategies (NFIS) because it can increase countries' resource mobilization and help them to build fiscal resilience.     

REER Imbalances and Macroeconomic Adjustments in the Proposed West African Monetary Union

With the spectre of the euro crisis hunting embryonic monetary unions, we use a dynamic model of a small open economy to analyse real effective exchange rate (REER) imbalances and examine whether the movements in the aggregate real exchange rates are consistent with the underlying macroeconomic fundamentals in the proposed West African Monetary Union (WAMU). Using both country‐oriented and WAMU panel‐based specifications, we show that the long‐run behaviour of the REERs can be explained by fluctuations in the terms of trade, productivity, investment, debt and openness. While there is still significant evidence of cross‐country differences in the relationship between underlying macroeconomic fundamentals and corresponding REERs, the embryonic WAMU has a stable error correction mechanism, with four of the five cointegration relations having signs that are consistent with the predictions from economic theory. Policy implications are discussed, and the conclusions of the analysis are a valuable contribution to the scholarly and policy debate over whether the creation of a sustainable monetary union should precede convergence in macroeconomic fundamentals that determine REER adjustments.     

INTEREST RATE PASS-THROUGH IN THE COMMON MONETARY AREA OF THE SACU COUNTRIES

We investigate the interest rate pass‐through in the four Common Monetary Area (CMA) countries of the South African Customs Union (SACU). We employ an empirical pass‐through model that allows for thresholds, asymmetric adjustment, and structural changes. We show that CMA bank lending markets exhibit quite some degree of homogenization as the pass‐through is often fast and complete. Deposit markets are somewhat more heterogeneous by showing differing degrees of interest rate stickiness and asymmetric adjustment. Policy makers should therefore be concerned about imperfect competition which may be at the heart of the remaining cross‐country differences in monetary transmission in the CMA.     

Government Debt Denomination Policies Before and After the EMU Advent

Through a cost-minimizing approach, this paper derives joint indicators to assess the efficiency of the mix of sovereign debt currencies between the countries belonging to the European Monetary Union (EMU). This theoretical insight enables us to explain why and how the introduction of the euro and the adoption of a common monetary policy may have led to significant changes in debt structure among EMU members, notably in favor of further euro-denominated debt. The interplay of intrinsic and strategic variables yields stylized facts that are consistent with country-specific empirical evidence. Following the sovereign debt crisis, we further emphasize the value-added of a coordinated debt issuance policy among EMU countries.     

The myth of a stable European money demand

Recent empirical studies suggest that an aggregate EC-wide money demand function is more stable than national money demand functions in the European Community. If true, this would facilitate monetary policy after Economic and Monetary Union. The evidence presented in this paper, however, shows that in general there is no relationship between the size of a currency area and the stability of its demand for money. I conclude that the stability of European money demand is a statistical artifact and has nothing to say about money demand stability in a future larger European currency area.     

Macroeconomic Policy Interaction under EMU: A Dynamic Game Approach

In this article, we study macroeconomic stabilization in the Economic and Monetary Union (EMU) using a dynamic game approach. With the aid of a stylized macroeconomic model, this article analyzes the transmission and interaction of national fiscal policies and monetary policy of the European Central Bank (ECB) in the EMU. A special focus is on the effects of labor market institutions in the participating countries and of the introduction of fiscal stringency criteria like those imposed in the Stability and Growth Pact.     

Measuring Multi‐Membership in Economic Integration and Its Trade Impact: A Comparative Study of ECOWAS and SADC

One of the intriguing aspects of African regional trade agreements (RTAs) is the extent of multi‐membership, where many African countries are members of more than one RTA. Using a gravity model for 25 countries and the years 1980‐2006, we measure the extent of multi‐membership and compare its impact in two major African regional blocs, Economic Community of West Africa States (ECOWAS) and Southern Africa Development Community (SADC). We find that the impact of multi‐membership critically depends on the characteristics of the multi‐membership of regional integration initiatives. We find a positive impact if an additional membership complements the integration process of the original regional integration initiative: overlapping memberships had a much stronger and significant positive effect on bilateral trade within ECOWAS compare with an insignificant impact within the SADC.
