Gender Inequalities and Economic Efficiency: New Evidence from Cassava‐based Farm Holdings in Rural South‐western Nigeria

Abstract: It is a widely accepted fact that persistent inequality between men and women constrains a society's productivity and ultimately slows its rate of economic growth. The economy pays for this inequality in reduced labour productivity today and diminished national output tomorrow. Motivated by this, the study aim is to assess the possibilities of enhancing productivity gains by improving the efficiency of small‐scale agriculture through gender‐responsive intra‐household allocation of resources in south‐western Nigeria. The study adopts a stochastic parametric decomposition method which yields efficiency measures that are not distorted by statistical noise to estimate the efficiency level of resource allocation by small‐scale cassava producers. The results indicate that average overall productive efficiency in the sample was 75.78 per cent, implying that small‐scale cassava farmers in the sample could reduce total variable cost by 24.22 per cent if they reduce labour, fertilizer, land and capital applications to levels observed in the changing input mix (technical efficiency) and then obtain optimal input mix for the given input prices and technology (allocative efficiency). The average technical efficiency and allocative efficiency indexes for the sample were 82.2 per cent and 92.2 per cent respectively. Also, evidence from empirical analysis of data from the male respondents showed that the average economic, technical and allocative efficiency indexes were 88.06 per cent, 89.34 per cent and 78.67 per cent respectively while the same computed for the female sample were 94.9 per cent, 74.85 per cent and 71.03 per cent respectively. Labour was the most limiting factor in cassava production suggesting that the technologies that enhance the productivity of labour are likely to achieve significant positive effects on cassava production. The paper shares the notion that producers' control over the means of production and impact of development are related and has influence on the economic efficiency and growth of society. Again, technical inefficiency constituted a more serious problem than allocative inefficiency, thus most cost savings will accrue to improvement in technical efficiency.     

Labor Market Inefficiency and Economic Restructuring: Evidence from Cross-Sectoral Data

The U.S. business cycle that began with the recession of 2001 featured both a “jobless recovery” and substantial structural change, leading some to ponder the “Sectoral Shift Hypothesis,” whereby restructuring purportedly creates labor market inefficiencies. Previous studies have analyzed aggregate time series, but new data permit a cross-sectoral comparison between restructuring and increased labor market inefficiency (as measured from sector Beveridge curves). This paper develops an estimation method and quantifies substantial increases in inefficiency during this period. However, contrary to the hypothesis, the increased inefficiency bears little relationship to the extent of sectors' structural change.     

Economic research and economic growth: Evidence from East Asian economies

Based upon page counts of articles published in 60 quality economics journals, the role of economic research is examined for five East Asian economies. In Hong Kong, causality runs bi-directionally between research productivity and economic growth; in Japan, the causal effects tend to be one direction from economic growth to research publications; in Korea and Taiwan, causality runs the other way around from publications to growth; and in Singapore, the causal effects are small and insignificant. Socioeconomic differences in each economy help to explain the various causal directions found.     

The Circumstances and Legal Consequences of Non‐GAAP Reporting: Evidence from Restatements*

Our study examines the circumstances of non‐GAAP financial reporting by 492 U.S. companies that announced restatements from 1995 to 1999. We focus on income statements to analyze the occurrence and resolution of litigation over restatements and explore the role of accounting items in bringing and resolving this litigation. We provide evidence on the pervasiveness of accounting misstatements, describe their nature, and show how, if at all, they affect litigation. We assess the nature of restatements by determining whether regular, recurring earnings from primary operations (core) or other components of earnings (noncore) are misstated, and we assess their pervasiveness by estimating the number of primary accounts misstated. In our sample, companies with core restatements have higher frequencies of intentional misstatements (fraud) and subsequent bankruptcy or delisting. Likewise, these companies have, on average, more material misstatements, more negative security price reactions to restatement announcements, and more negative security price changes over the six months preceding and following restatement announcements. However, controlling for these and other factors, we find a significant association between accounting items and litigation, whether occurrences or resolutions. Specifically, core restatements — driven primarily by misstatements of revenue, a component of core earnings — and more pervasive restatements each play a role, while misstatements of noncore earnings alone do not.     

Economic and environmental outcomes of economic transition: Evidence from a quasi-experiment in China

China is actively seeking an economic transition to achieve high-quality development, which means economic growth and environment improvement. This paper evaluates the economic and environmental effects of a pilot zone for transformation of growth engine (TGE) policy in Shandong province, China. We collected the monthly data of 73 prefecture-level cities in five provinces of central and eastern China from 2015 to 2020, then used the boundary discontinuity difference-in-differences (BD-DID) for identification. The results show that this pilot policy has effectively improved environmental quality while achieving economic growth, but the core zones did not perform well in environmental improvement. Analysis of the mechanism shows that innovation, infrastructure and pollution control are important channels of the TGE policy in improving the economy and environment.     

Imperfect Competition, Economic Miracle, and Manufacturing Productivity Growth: Empirical Evidence from Taiwan

Several recent studies on total factor productivity (TFP) concluded that the East Asian economies benefited little from TFP growth. This study claims that the failure by previous studies to consider the effect of net indirect taxes and market imperfections resulted in the underestimation of the share of the contribution of labor input to factor income, which consequently led to the overestimation of capital share and understatement of TFP growth. Therefore, this study has modified the conventional approach of calculating factor shares by taking account of net indirect taxes and market imperfections and used the modified approach to estimate TFP growth in 16 Taiwanese manufacturing industries during the period 1979–1999. The conclusion drawn by the study is that TFP growth was the driving force behind the success of Taiwan's manufacturing industries, although many of these industries experienced a sharp decline in TFP during the 1990s.     

Land Inheritance and Schooling in Matrilineal Societies: Evidence from Sumatra

This paper explores statistically the implications of the shift from communal to individualized tenure on the distribution of land and schooling between sons and daughters in matrilineal societies, based on a Sumatra case study. The inheritance system is evolving from a strictly matrilineal system to a more egalitarian system in which sons and daughters inherit the type of land which is more intensive in their respective work effort. While gender bias is either non-existent or small in land inheritance, daughters tend to be disadvantaged with respect to schooling. The gender gap in schooling, however, appears to be closing for the generation of younger children.     

Financial Liberalization Policies and Economic Growth: Panel Data Evidence from Sub‐Saharan Africa

Abstract: The paper conducts an empirical investigation into the effects of financial liberalization policies on the growth of 19 countries in sub‐Saharan Africa (SSA). Two indexes are constructed which measure the gradual progression and institutional changes involved in financial liberalization. Because these indexes track specific financial liberalization policies, they provide better measures of financial liberalization than the indicators of financial development often used in the literature. Panel data estimates show a significant positive relationship between economic growth and financial liberalization policies. Our results are robust to alternative specifications of the model, and also across slow‐ and fast‐growing countries.     

The Impact of Political Competition on Economic Growth: Evidence from Municipalities in South Africa

This paper examines the impact of political competition on economic growth. In this paper, I show that internal political dynamics, distinct from the type of political system, can having different effects on growth. Using results from the 1994 and 1999 elections in South Africa, I show that municipalities with higher levels of political competition have shown lower levels of economic growth. I use individual level surveys to show that this political competition is associated with political paralysis, dissatisfaction with the current democracy and government and lower optimism about the future.     

An Economic Analysis of Audit and Nonaudit Services: The Trade‐off between Competition Crossovers and Knowledge Spillovers*

In this paper, I present a model in which both markets for audit services and nonaudit services (NAS) are oligopolistic. Accounting firms providing both audit services and NAS will employ oligopolistic competition in each of these markets. In addition to auditors' gaining “knowledge spillovers” from auditing to consulting or vice versa, oligopolistic competition in one market will influence the counterpart in the other market ‐ what I call “competition crossovers”. Although scope economies due to knowledge spillovers (for example, cost savings) are always beneficial to auditors, such benefits can entice accounting firms to adopt strategies (for example, price reductions) to compete aggressively in the audit market so that some, or all, firms become worse off. A trade‐off arises between these two economic forces in the two oligopolistic markets. Given the trade‐off between competition crossovers and knowledge spillovers, accounting firms may not reduce their audit prices, even though supplying NAS enables firms to decrease auditing costs — a nontrivial impact of oligopolistic competition in two markets on audit pricing. The empirical implication of my results is that because of competition‐crossover effects between the auditing and consulting service markets, finding empirical evidence for knowledge‐spillover benefits is likely to be difficult. Control variables for “audit‐market concentration” concerned with competition‐crossover effects and “auditor expertise” concerned with knowledge‐spillover benefits should be included in audit‐fee regressions to increase the power of empirical tests. With regard to policy implications, my analyses help explain the impact of the Sarbanes‐Oxley Act on “market segmentation” and, hence, the profitability of accounting firms.     

Gender norms and marriage satisfaction: Evidence from China

This paper examines the association between the traditional gender division norm — “men are breadwinners, and women are homemakers” — and the marriage satisfaction of each gender using Chinese couple-level data. The results reveal that married couples tend to be less satisfied with their marriage if the wife earns more than the husband. Moreover, it seems that the drop in the husband's marriage satisfaction matters more for the drop in the couple's overall marriage satisfaction. By exploring the difference between husbands and wives in their attitudes in terms of economic contribution and housework contribution, we confirm that husbands may have a specific self-image regarding the traditional gender division norm, and can also respond to the wives' gender role preference.     

Early Experience and Later Outcomes of Education: Schooling Transition Evidence from Indonesia

This paper investigates the effect of early school experience on later educational attainment. Using the Indonesia Family Life Survey (IFLS), we find that students who repeat a grade at primary school are less likely to progress to junior high school. We also find that grade retention is associated with lower rates of transition from junior high school to senior high school. The relationship persists across years and samples. Meanwhile, the age of students when starting school and the hours they spend there have limited effects on whether they continue their schooling. We also observe that the effects of parental education and household income on the transition of students from primary school to junior high school are weakening. Given the long-term impact of grade retention, policymakers should be cautious when recommending it for underachieving children and should look for alternatives.
