With the growth of income at the global level, the World Bank data show that there are rising levels of income disparity across countries, groups, regions and within the countries. This fact otherwise hints at the inter-country divergence in incomes, particularly between the developed and developing countries of the world. This chapter, therefore, attempts to examine the convergence or divergence in credit, GDP and HDI across the 10 selected countries for the period of 1990–2019 applying the neoclassical growth approach and the time series approach. The results of the exercise in line with the neoclassical theories on absolute convergence and sigma convergence show that the countries are unquestionably converging in GDP and HDI with mixed results in case of credit. The results of convergence in GDP and HDI in all the countries and their developed and developing counterparts provide a possible explanation as to why the cross countries’ income inequalities as well as world inequality in income and development are reducing over time. On the other hand, the results of the time series approach display that credit and HDI are converging in both absolute and conditional terms but the countries are converging in conditional terms only for GDP. Thus, the claims of the World Bank are not valid for the selected countries in the chapter, rather, they can be verified by taking other countries and groups into consideration.

This article investigates the validity of the different types (conditional, unconditional, deterministic, stochastic) of ß-convergence in per capita GDP for EU-28 and EU-19 between 1990 and 2019.

The study uses nonstationary heterogeneous panel-data methodology.

The panel data reveal that both conditional and unconditional ß-convergence are valid in EU-28 countries However, only conditional convergence exists in EU-19 countries; group-specific findings show that the income levels of 10-EU countries converge toward the EU-19 average and 11-EU countries converge to the EU-28. The convergence speed to EU average varies between 15 and 18%. The robustness of the augmented mean group (AMG) findings are checked with common correlated effects mean group (CCEMG) and are consistent. Moreover, panel unit root tests are applied to examine the stochastic and deterministic convergence of the average EU per capita income in the two groups of EU economies. The findings show no evidence of deterministic or stochastic convergence in EU countries. Besides, conditional convergence has not been experienced in countries such as Bulgaria, Croatia, Czech Republic, Hungary, Latvia, Malta, Romania, Slovakia and Slovenia, which are new members of the EU. As a remarkable aspect of the study, the evidence suggests that the Brexit is economically rational for the UK.

The growth and convergence processes of economies differ from each other. Convergence studies in the literature are generally based on the cross-section OLS methodology. In this context, the study is one of the rare studies to examine convergence using heterogeneous panel techniques and allows the convergence of countries to the EU average to be analyzed individually.

The purpose of this paper is to investigate convergence or divergence trends at global scale.

The paper questions the methodology and findings of the conventional convergence literature using linear OLS models. It introduces polynomial (quadratic) weighted least square (WLS) regression analysis to explore whether a number of economic performance indicators follow a non‐linear pattern of change.

The results indicate the formation of two groups in the world: a convergence one, including countries with low to medium‐high development levels, and a divergence one including countries with medium‐high to very high development levels.

Data availability after 1990 (for the composite indicators).

The findings shed light on important issues, such as the decrease of economic disparities between countries, the prospects for global economic convergence, and the development of a more equal world. Apart from obvious policy implication such findings are also of theoretical significance, providing a basis to check (indirectly) the validity of alternative growth theories.

This is the first paper (to the authors' knowledge) that explores world convergence/divergence employing quadratic WLS regression analysis with a number of economic indicators. WLS regressions enable the removal of the impact of country size on results, whereas non‐linear modelling allows the possibility of multiple equilibria and different development trajectories to be taken into account. Finally, the employment of various economic‐performance indicators (simple and composite) works as a cross‐check of validity for the results provided.

A major lesson of the European Monetary Union (EMU) crisis is that serious disequilibria result from regional monetary arrangements not designed to be robust to a variety of shocks. The purpose of this paper is to assess these disequilibria within the Economic and Monetary Community of Central Africa (CEMAC), West African Economic and Monetary Union (UEMOA) and Financial Community of Africa (CFA) zones.

In the assessments, monetary policy targets inflation and financial dynamics of depth, efficiency, activity and size while real sector policy targets economic performance in terms of GDP growth. The author also provides the speed of convergence and time required to achieve a 100 percent convergence.

But for financial intermediary size within the CFA zone, findings, for the most part, support only unconditional convergence. There is no form of convergence within the CEMAC zone.

The broad insignificance of conditional convergence results has substantial policy implications. Monetary and real policies, which are often homogenous for member states, are thwarted by heterogeneous structural and institutional characteristics, which give rise to different levels and patterns of financial intermediary development. Therefore, member states should work towards harmonizing cross‐country differences in structural and institutional characteristics that hamper the effectiveness of monetary policies.

The paper provides warning signs to the CFA zone in the heat of the Euro zone crises.

By incorporating the role of nonperforming loans (NPLs), the study aims to assess the impact of global financial crisis (GFC) on the intermediation efficiency of Indian banks for the period of 1998/99 to 2016/17.

To obtain efficiency level of Indian banks, this study applied sequential data envelopment analysis (DEA) based directional distance function (DDF) approach, which performed simultaneous expansion of desirable output and reduction of undesirable output in the bank's loan production structure. Additionally, using fixed effect regression approach in the panel data framework, this study assesses both the phenomenon of σ- and unconditional β-efficiency convergence in public sector banks (PSBs), private banks (PBs), foreign banks (FBs) and overall scheduled commercial banks (SCBs) during the pre-crisis, crisis and post-crisis years in India.

Irrespective of the bank's production model, the evidence suggests that the accounting NPLs as an undesirable output significantly deteriorating the intermediation technical efficiency levels of Indian banks, especially after the crisis years until the last year of the study period. This reflects that Indian banks failed more to achieve their financial intermediation objective in the post-crisis years as compared to the crisis and pre-crisis years. In-depth, statistical evidence of commercial bank ownership groups reveals that public sector banks exhibit a higher level of efficiency in pursuance of traditional loan-based activity followed by private and foreign banks. The study also found the existence of sigma convergence in technical efficiency levels of Indian banks and ownership groups as well.

This study is perhaps the first one, which present the robust evolution of Indian banks intermediation efficiency by taking into account both endogenous (i.e. NPLs as an undesirable output and equity as a quasi-fixed input in the bank production process) crisis and exogenous (i.e. global financial and economic stress) crises. Moreover, none of the existing studies have conducted sub-period wise analysis to show the apparent occurrence of both convergence properties in technical efficiency, adding novelty in the literature.

This paper aims to examine the impact of corruption and bureaucracy on economic growth in Greece as measured by the growth rate of per capita GDP. Also, using the mean per capita GDP of the EU as a benchmark, it seeks to investigate the convergence timing of Greece with the EU.

The empirical approach taken is based on beta convergence theory.

The results confirm the negative impact of bureaucracy and corruption on economic growth. However, the corruption exerts a more significant influence on growth than bureaucracy. Also, the timing of convergence of Greece with the EU is found to be 37 years.

The robustness of these results is based on the use of a relatively new econometric method which is the Markov conditional bootstrap.

The investment development path of emerging markets’ MNEs is significantly different from the developed (TRIAD) world’s MNEs; BRIC MNEs seem to have taken a different trajectory on account of various political and economic reasons, ranging from the ‘forms of entry’ to ‘country-specific advantages’ (Tulder, R. V. (2010). Toward a renewed stages theory for BRIC multinational enterprises? A home country bargaining approach. In K. P. Sauvant, G. McAllister, & W. A. Maschek (Eds.), Foreign direct investments from emerging markets: The challenges ahead (pp. 61–74). New York, NY: Palgrave Macmillan). Yet, some believe that in the long run the internationalization strategy of the developed world MNEs and BRIC MNEs will converge. Internationalization strategies as measured by OFDI depend on various macroeconomic determinants such as income, interest rate, openness of the economy, etc. The chapter intend to highlight, the significant difference between these two groups of countries on account of diverse political reforms towards internalization of firms, yet see if these different countries might converge.

Regression analysis examines the significance of the role of home government by testing the effect of governance indicators; that is voice and accountability, on OFDI. It further, tests for convergence of internationalization strategies of the two historically divergent groups, also, it tests convergence amongst the BRIC nations. Along with forecasting, time series analysis is also employed to examine convergence using univariate sigma convergence techniques.

Impact of voice and accountability is significant but it hinders OFDI for BRIC nations, while it promotes OFDI for TRIAD & ALL. Moreover, the analysis found the existence of convergence, that is BRIC will catch up with TRIAD, but though convergence exists amongst BRIC if we take a long span of time (45 years), it is absent in short span of time (19 years), as lately BRIC have shown divergent tendency.

Small sample size in multivariate regression analysis. Also, the governance indicator, that is voice and accountability, is perception based, and missing gaps in data for governance indicator is filled using interpolation.

Empirically testing the convergence of BRIC nations with the developed world. A univariate time series analysis is undertaken to understand each country’s heterogeneous FDI outflows and to address the research gap in existing forecasting literature. In addition, the comparison specifically between the Emerging Market Economies, that is the BRIC nations and the developed world gives some useful insights. This chapter ascertains the impact of governance indicator on OFDI; empirical literature shows such analysis for IFDI & FDI, but OFDI is rarely been dealt with.

Assessment of African financial development dynamic convergences in money, credit, efficiency and size. The paper aims to discuss these issues.

The empirical evidence is premised on 11 homogenous panels based on regions (Sub-Saharan and North Africa), income-levels (low, middle, lower-middle and upper-middle), legal-origins (English common-law and French civil-law) and religious dominations (Christianity and Islam). The paper examines convergence in financial intermediary dynamics of depth, efficiency, activity and size.

Findings suggest that countries with small-sized financial intermediary depth, efficiency, activity and size are catching-up countries with large-sized financial intermediary depth, efficiency, activity and size, respectively. The paper also provide the speeds of convergence and time necessary to achieve a full (100 percent) convergence.

The presence of strong links among African banking sectors may present little opportunity for portfolio diversification. The convergence patterns show positive steps toward regional integration. As a policy implication, African governments should not relent in structural and institutional reforms.

It is the first critical assessment of convergence in financial intermediary development dynamics in the African continent.

A spectre is hunting embryonic African monetary zones: the European Monetary Union crisis. The purpose of this paper is to assess real, monetary and fiscal policy convergence within the proposed WAM and EAM zones. The introduction of common currencies in West and East Africa is facing stiff challenges in the timing of monetary convergence, the imperative of central bankers to apply common modeling and forecasting methods of monetary policy transmission, as well as the requirements of common structural and institutional characteristics among candidate states.

In the analysis: monetary policy targets inflation and financial dynamics of depth, efficiency, activity and size; real sector policy targets economic performance in terms of GDP growth at macro and micro levels; while, fiscal policy targets debt-to-GDP and deficit-to-GDP ratios. A dynamic panel GMM estimation with data from different non-overlapping intervals is employed. The implied rate of convergence and the time required to achieve full (100 percent) convergence are then computed from the estimations.

Findings suggest overwhelming lack of convergence: initial conditions for financial development are different across countries; fundamental characteristics as common monetary policy initiatives and IMF-backed financial reform programs are implemented differently across countries; there is remarkable evidence of cross-country variations in structural characteristics of macroeconomic performance; institutional cross-country differences could also be responsible for the deficiency in convergence within the potential monetary zones; absence of fiscal policy convergence and no potential for eliminating idiosyncratic fiscal shocks due to business cycle incoherence.

As a policy implication, heterogeneous structural and institutional characteristics across countries are giving rise to different levels and patterns of financial intermediary development. Thus, member states should work towards harmonizing cross-country differences in structural and institutional characteristics that hamper the effectiveness of convergence in monetary, real and fiscal policies. This could be done by stringently monitoring the implementation of existing common initiatives and/or the adoption of new reforms programs.

It is one of the few attempts to investigate the issue of convergence within the proposed WAM and EAM unions.

Forestry is an integral part of an economy. It not only maintains the balance of the ecosystem but provides sustainable livelihood to the forest-fringe dwellers, apart from being a huge source of revenue for the government. Hence, proper management of the forest resources is an important concern for the economists. On the other hand, convergence of natural resources is one of the hot cakes of discussion for the economists. In this study, the authors have considered three forest regions of West Bengal; these three being the largest forest areas hold an important position in West Bengal’s economy. Here, the authors have considered the whole of dryland forestry that covers the arid and semi-arid districts of western part of the state. They have also considered the forestry of Jalpaiguri and Cooch Behar districts that cover the sub-Himalayan forestry of North Bengal and mangrove forestry of South 24 Parganas district. The authors have used time-series data for the time period 1980–2019 and performed the Absolute Beta Convergence and Sigma Convergence Analysis as well as Conditional Beta Convergence of the total forest products of these three regions. In this study, the authors have found the existence of both forms of beta convergence but for variations, a divergence has been observed. The authors have also used the data from 2000 to 2019 on various aspects of income from forestry and performed the three forms of tests, like that of total forest products and observed similar type of results, that is, beta convergence of both forms but sigma divergence. The findings of this study ask for serious steps by the government bodies, since the decreasing rates are the causes of worries.
