Foreign exchange exposure of exporting and importing firms

The existing literature reports insignificant `total' exposure for multinational or exporting firms, where total exposure incorporates both firm-specific and macroeconomic effects. We propose a dual-effect hypothesis to explain this result which seemingly contradicts conventional wisdom. According to our proposed hypothesis, firms are affected by both the domestic economy and foreign markets. These effects are at least partially offsetting for exporters and additive for importers. The resulting predictions of insignificant total exposure for exporters and positive total exposure for importers are borne out in our tests. The literature also reports insignificant `residual' exposure for multinationals or exporting firms, where residual exposure estimates the firm-specific exposure. This result is explained by biases in the residual exposure estimates introduced by the choice of the value-weighted market index as the control portfolio. We propose an equally-weighted portfolio of purely domestic firms as an alternative portfolio to reduce such biases and report significantly negative exposure for exporters and significantly positive exposure for importers, as predicted by theory.     

Population growth and food supply in sub-Saharan Africa

It is argued in this article that sub-Saharan Africa, given its present institutions and endowments of capital and technology, is already dangerously close to overpopulation. The rapid growth of its population projected for the next decades will greatly increase human misery and depress economic development. Specifically, rapid population growth will have disastrous effects on the region's ability to increase exports and provide people with food. There must be a search for new ways in which these effects could be mitigated. In sub-Saharan Africa fertility either continues to be very high or is increasing, in part due to some decline in traditional practices that reduce fertility, such as prolonged breastfeeding. This situation and the expectation of declining mortality imply that African population growth may increase further. Currently, population in sub-Saharan Africa is about half that of India and a third of China. There are 2 main reasons why reduced fertility in the next few decades is unlikely in sub-Saharan Africa as a whole: Africa has low literacy, high infant and child mortality, and low urbanization; and average African fertility rates may even increase for the next 20 years or so. The question that arises is what are the implications of continuing and rapid population growth for the African food supply. The region's cereal production is largely restricted to 4 grains, i.e., millet, sorghum, maize, and rice. The volume of grain production is less, by weight, than 60% of the production of roots and tubers. There are 2 main differences between the output of these crops in sub-Saharan Africa and the rest of the world: yields/hectare are lower in Africa than in elsewhere; and yields have generally been decreasing or largely constant in Africa. The low productivity has several causes. Today, population pressure has brought diminishing returns to traditional agriculture in much of the Sahel and the savanna, in parts of East Africa, Southern Africa, and parts of the West African forest belt. There is also the absence of the Green Revolution, i.e., the use of new high yielding seeds and new technologies in agriculture that has led to marked increases in yields in most other parts of the world. A totally different and more productive agriculture might evolve if African governments were to fundamentally change their vision. Existing production technology could allow substantial increases in the yields of many crops if some basic changes were made in the policies affecting agriculture. A way to achieve such change would be to make farming profitable. The effect of population growth in diminishing returns to agriculture also lends urgency to the need for family planning. Generally, population policy in Africa badly needs strengthening.     

The relationship between culture and tax evasion across countries: Additional evidence and extensions

This study builds on the work of Tsakumis et al. [Tsakumis, G. T., Curatola, A. P,. & Porcano, T. M. (2007). The relation between national cultural dimensions and tax evasion. Journal of International Accounting, Auditing and Taxation, 16, 131-147] by conducting further empirical analysis of the relationship between Hofstede's [Hofstede, G. H. (1980). Cultures consequences: International differences in work-related values. Beverly Hills, CA: Sage Publications] cultural dimensions and tax evasion across countries using multiple measures of tax evasion to gain additional evidence on the subject. Moreover, this study extends the preliminary international tax evasion model developed by Tsakumis et al. [Tsakumis, G. T., Curatola, A. P,. & Porcano, T. M. (2007). The relation between national cultural dimensions and tax evasion. Journal of International Accounting, Auditing and Taxation, 16, 131-147] to examine, along with culture, the impact of legal, political, and religious variables on tax evasion across countries. Based on data from 47 countries, and after controlling for economic development, the regression results indicate that the higher the level of uncertainty avoidance and the lower the level of individualism, legal enforcement, trust in government, and religiosity, the higher is the level of tax evasion across countries. These findings remain robust to multiple measures of tax evasion. Government policymakers should find the results of this study useful in assessing the likelihood of tax evasion from cultural, legal, political, and religious perspectives, and in developing tax reform policies to reduce tax evasion.     

Sais work against corruption in Scandinavian,South-European and African countries: An institutional analysis

International pressures on Supreme Audit Institutions (SAIs) to fight corruption are increasing. Nevertheless, SAIs lack a clear mandate and may appear ineffective in their anticorruption work. Using an institutional approach, this paper compares the cases of seven SAIs from Scandinavian, South-European and African countries to better understand how these institutions perceive their role in fighting corruption. Our article demonstrates that the way SAIs organize their work cannot simply be explained by the countries' level of corruption. Rather, efforts to fight corruption reflect the ways in which coercive, mimetic and normative pressures interact with institutional logics to guide the SAIs' work. We conclude that the influence of INTOSAI still appears to be limited, and it needs increased institutional recognition if it is to be effective in harmonizing SAIs' work worldwide to fight corruption.     

The dark side of transparency in developing countries: The link between financial reporting practices and corruption

This paper examines the impact of financial reporting practices on corruption obstacles for about 150,000 firms across 143 mostly developing countries from 2006 to 2019. We document a strong positive relationship between the production of audited financial statements (AFS) and corruption obstacles (CO) faced by the firm. We argue that in a corrupt business environment, rent-seeking bureaucrats use the credible financial information to optimize their bribe demands. Our baseline results remain robust after addressing endogeneity concerns. We further show that country-level institutional quality has a moderating effect on the AFS-CO relation. The evidence from surveying entrepreneurs also provides qualitative support for our empirical findings. Our study sheds light on a previously under-explored adverse consequence of transparency - exposure to corrupt bureaucrats where institutions are weak.     

The causes and consequences of a poor-performing emerging stock market in sub-Saharan Africa: The case of the Ghana Stock Exchange

The Ghana Stock Exchange (GSE) is one of the premier stock exchanges in Africa and has demonstrated sound performance since trading commenced in 1990. This study shows, however, that many Ghanaians are ignorant about the location and functions of the GSE. Several firms are discouraged from operating on the GSE due to the high rate of inflation, slow services and perceived high risk. Respondents agree that GSE provides adequate information on stock indexes and the price of foreign stocks but inadequate information on new securities issues and the number of rises and falls. TV, radio and newspapers are the most effective media that inform Ghanaians about the activities of the GSE but there is no structured method of disseminating information about GSE activities.

Developing countries converging with developed-country accounting standards: Evidence from South Africa and Mexico

I examine the usefulness (relevance and timeliness) of earnings announcements in two emerging markets, the Johannesburg Stock Exchange (JSE) and the Bolsa Mexicana de Valores Stock Exchange (BMV). A weighted least-squares regression is used to test the association of book values of earnings and equity with firm market value. I find that, on JSE and BMV, earnings and/or book value of equity are value relevant in explaining stock prices. I also find that this association is greater in 2000 as compared to 1998 on the BMV. Regarding timeliness, I find that earnings announcements are accompanied by unusually different returns on JSE, but not on BMV. Market infrastructure, specifically insider-trading rules, may explain BMV results. I suggest that accounting and market infrastructure interact and that such interaction is valuable input to the Financial Accounting Standards Board (FASB) and International Accounting Standards Board (IASB) in their deliberations regarding one set of accounting regulations for all countries.     

The effects of International Financial Reporting Standards,auditing and legal enforcement on tax evasion: Evidence from 37 African countries

This study examines the significance of International Financial Reporting Standards (IFRS), audting and legal enforcement on tax evasion for a group of 37 African countries for the period 2008–2017. These countries were subsequently regrouped into subsamples of four clusters. Three-stage least square regression was used for the analysis. The results indicate that there is a negative and significant relationship between IFRS and tax evasion in some clusters (i.e., early IFRS adopters and strong legal enforcers). The other clusters (late IFRS adopters and weak legal enforcers) have a similar sign of coefficient though statistically insignificant. Moreover, evidence suggests that adoption and application of IFRS lead to improved financial reporting quality and lessen tax evasion in some African jurisdictions. Additionally, legal enforcement is found to be statistically significant in relation to tax evasion in two clusters (i.e., early IFRS adopters and strong legal enforcers). Some African countries are slow or ineffective in adopting and implementing IFRS, which by itself cannot improve tax compliance. IFRS can only achieve its objective when there is strong legal enforcement (e.g., control of corruption, rule of law, effective regulatory framework, voice and accountability, strong monitoring, and auditing to promote transparency). More evidently, in contrast to weak legal enforcers, countries with strong legal enforcement have high IFRS compliance, which can strengthen auditing and reporting standards and hence, improve tax compliance.

The distributional impact of access to finance on poverty: evidence from selected countries in Sub-Saharan Africa

This paper uses pooled household-level data from thirteen Sub-Saharan African (SSA) countries conducted between 2014 and 2018 to examine the impact of access to finance on household wealth. The few studies that investigated this relationship in the past apply a linear estimation, and thus inadvertently assume a uniformly distributed effect across all levels of poverty. This study examines the heterogeneous impact of access to finance along the entire wealth distribution line using a Re-centered Influence Function (RIF) regression model. We adopt a unique approach to this research problem by constructing an asset-based wealth-index for each country, and use it as a proxy for poverty, and thus get around the problem of non-reported and bracket income. Further, to eliminate potential endogeneity, an instrumental variable quantile approach is implemented. Results indicate that the unconditional effect of access to finance on poverty is non-homogenous. The effect is higher at higher quantiles of wealth and very low at the bottom of the wealth index, suggesting that the extension of formal financial services disproportionately benefits wealthier households more than the very-poor categories.     

The internationalization of British professional accounting: the role of the examination exporting bodies

This paper extends the seminal study of the role of the UK accounting profession undertaken by Johnson and Caygill (1971). It is argued that the influence of the British accounting profession upon overseas countries has changed significantly from the export of UK accountants to the export of examinations. This has greatly facilitated the attainment of a UK qualification by overseas nationals and thus enhanced the international influence of UK accounting principles and practices. The possible implications of this trend for importing countries are also explored. Finally, the paper discusses the impact of this new development upon the professional body which is the leading provider of overseas examinations.     

Corporate profitability and the global persistence of corruption

We examine the persistence of corporate corruption for a sample of privately-held firms from 12 Central and Eastern European countries from 2001 to 2015. Using publicly available information and stochastic frontier analysis, we create a proxy for corporate corruption based on a firm's internal inefficiency. We find that corruption enhances a firm's profitability. A channel analysis further reveals that inflating staff costs is the most common approach by which firms divert funds to finance corruption. In spite of corruption's negative effects on a country's economy, we conclude that it persists because of its ability to improve corporate profitability. We refer to this effect as the Corporate Advantage Hypothesis.     

Public corruption and the allocation of government contracts

Public corruption in the government procurement process is rampant and its cost is huge, even among developed countries. Some scholars estimate that about 20%–30% of the values of government projects are lost due to public corruption. In this paper, we examine how public corruption impacts the allocation of U.S. federal contracts. Using the U.S. Department of Justice corruption convictions data and the federal contract data from 2000 to 2018, we find that firms located in more corrupt states receive more federal contract dollars, more important contracts in terms of their contributions to firm revenues, and contracts with higher visibility among federal contractors. We construct an influence/favoritism index that takes into account defense contracts, cost-plus contracts, and multi-year contracts, and document that the index is positively related to corruption levels. These results hold after we conduct several robustness tests, including 2SLS regressions, propensity-score matching analysis, and using alternative corruption measures. Our empirical findings are consistent with the hypothesis that corruption plays an important role in how federal contracts are allocated.     

The influence of political factors on commercial banks in Central European countries

This study examines the impact of political factors on the behaviour and performance of commercial banks in 11 Central European countries from 1995 to 2008. Using a unique dataset of commercial banks and political factors, we find that state-owned banks report significantly smaller net interest income ratios during the years of parliamentary elections. The proxy cumulative amount of net interest income lost by state-owned banks during the election years equals, on average, 0.38% of each country's GDP. The decrease in the profitability of state-owned banks is caused primarily by the lower interest rates charged on loans. In contrast, we document that the lending growth of state-owned banks is not affected by the political cycle. Hence, to a certain extent, this study supports the view that state-owned banks constitute a tool that serves political goals in Central European countries.     

The role of auditing in the fight against corruption

The purpose of this paper is to analyze how various types of auditing may contribute to fight corruption. While previous literature has primarily addressed auditing's ability to prevent corruption, this paper systematically explores auditing's potential to detect corruption. It argues that financial auditing has excluded corruption from the definition of fraud and instead classified it as ‘non-compliance with laws and regulations’. The main arguments for this exclusion is that corruption leaves no material errors in financial statements and no evidence for the auditor to follow. The paper refutes this, arguing that commercial and political corruption creates misstatements in the financial statements of the corruption giver's organization as well as the corruption receiver's organization. Thus, if auditing is to gain a more prominent role in the fight against corruption, auditing standards must include corruption in the definition of fraud, private and public sector auditors need to cooperate and exchange information, auditing techniques to detect corruption should be employed, and the auditing profession must embrace effective preventive measures such as anti-corruption certifications.
