Nutrients: Impacts and Determinants

Understanding the determinants of nutrient intake and the influenceof nutrition on performance is critical in designing policiesto alleviate hunger and malnutrition. A series of studies undertakenby the authors, which are synthesized here, analyzes the influenceof prices, income, and women's schooling on the nutrient intakeof those in developing countries and the effect of nutritionon health, productivity, wages, and fertility. These studiessuggest that the impact of food price increases may be strong,particularly among those with the lowest incomes, that the growthof income may be less likely to improve nutrient intake thanhas been suggested by others, and that women's schooling isimportant in improving nutrition. These studies also indicatethat nutrition exerts a positive influence on wages, productivity,and fertility. Our limited knowledge of the role and determinantsof nutrition is reflected in the finding of unduly strong effectsof seasonality on price-nutrition relations and the lack ofa direct association between nutrition and health.     

National income taxation and the geographic distribution of population

We study how different national taxation schemes interact with geographic variation in productivity and consumption amenities in determining regional populations. A neoclassical migration equilibrium model is used to analyze the current nominal income tax system in Norway. The analysis is based on estimated regional income differences accounting for both observable and unobservable individual characteristics and the value of experience. Given regional differences in incomes and housing prices, quality of life and productivity are calibrated to model equilibrium. Compared to an undistorted equilibrium with lump-sum taxation, nominal income taxation creates a disincentive to locate in productive high-income regions. The deadweight loss due to locational inefficiencies is 0.18% of gross domestic product (GDP). We study real income taxation and equal real taxes as alternative tax systems. Both alternatives generate a geographic distribution of the population closer to the undistorted equilibrium, and hence with lower deadweight loss. In an extension of the analysis, we take into account payroll taxes. The existing regionally differentiated payroll taxes to the disadvantage of cities generate a deadweight loss of 0.22% of GDP in an economy with lump-sum income taxation. The two distortionary taxes interact and strengthen each other and the combined distortionary effect of income and payroll taxation in the Norwegian system is 0.46% of GDP.     

The Determinants of the Volatility of Fiscal Policy Discretion

This paper investigates the determinants of the volatility of fiscal policy discretion. Using a linear dynamic panel data model for 113 countries from 1980 to 2006 and a system‐GMM estimator, we find that an increase in the number of episodes of government crisis, less democracy and presidentialist systems raise the volatility of the discretionary component of fiscal policy. Additionally, we show that countries with larger populations and less flexible exchange rate systems are more insured against uncertainty about the conduct of fiscal policy. Our results are robust to various regional dummy variables, different subsets of countries and the presence of high inflation and crisis episodes.     

Doha Merchandise Trade Reform: What Is at Stake for Developing Countries?

The LINKAGE model of the global economy and the latest GlobalTrade Analysis Project (GTAP) database (version 6.05) are usedto examine the impact of current merchandise trade barriersand agricultural subsidies and possible reform outcomes of theWorld Trade Organization’s (WTO’s) Doha DevelopmentAgenda. The results suggest that moving to free global merchandisetrade would boost real incomes in Sub-Saharan Africa proportionatelymore than in other developing countries or in high-income countries,despite the terms of trade loss in parts of that region. Particularattention is given to agriculture, as farmers constitute thepoorest households in developing countries but the most assistedin rich countries. Net farm incomes would rise substantiallyin Sub-Saharan Africa and other developing country regions,alleviating rural poverty. Partial liberalization could movethe world some way toward those desirable outcomes, the moreso the more developing countries themselves cut applied tariffs,particularly on agricultural imports.     

The Drivers of Sovereign CDS Spread Changes: Local Versus Global Factors

We use daily data for a panel of 34 countries to investigate regional differences in sovereign credit default swaps (CDS) spread determinants and the significance of local versus global market factors. Similar to prior studies, we find a high level of commonality among CDS spreads, but our results show that this effect is stronger in Latin American CDS. The results of our quantile panel regression model show that although global forces drive spreads across the conditional distribution, changes in credit ratings are significant in explaining CDS spreads only in the upper quantiles. We also confirm the existence of regional differences in spread determinants.     

Determinants of Labor Productivity in MENA Countries

This article scrutinizes the role of various determinants (compensation, human capital, oil rent, trade, financial development, innovation, and industrialization) in labor productivity in the context of Middle East and North Africa (MENA) countries. Dynamic-OLS and fully modified-OLS were applied to analyze panel time series data over the period 1980 to 2014. It was found that size of employment and compensation are negatively associated with labor productivity, while human capital and capital stock are positively associated with it; and that oil rent, financial development, trade openness, and industrial value addition play significant roles in promoting labor productivity. Finally, innovation was found to be an important factor in accelerating labor productivity. These findings are important for labor policy making in MENA economies.     

The Impact of Public Expenditure and International Trade on Agricultural Productivity in China

The “industry nurturing agriculture” reforms and World Trade Organization accession led to dramatic growth in public expenditure and international trade in China’s agricultural sector. This article aims to estimate the effects of public expenditure and trade on agricultural productivity in China for 2004–2015. A semi-parametric production function with shape constraints is introduced to derive more accurate productivity before the productivity determinants are analyzed with an emphasis on public expenditure and trade. The empirical result shows that public expenditure and exports can effectively improve agricultural productivity, while imports have no significant effects. Policy implications are discussed in the context of supply-side reforms.     

What is the major determinant of cross-border banking flows?

This study examines the major determinant of cross-border credit flows through global banks across 70 countries. Employing a Bayesian dynamic latent factor model, we decompose volatilities of banking flows into the contribution of a global common factor, regional common factor, and country-specific factor. The results indicate that the global and regional common factor explains about 40–50 percent of volatility in overall cross-border banking flows. In particular, the contribution of the global common factor increased in the 2000s. Simultaneously, main determinants are largely heterogeneous across countries: this implies that the desirable policy response to credit inflows may differ for each host country.     

Agriculture and aggregate productivity: A quantitative cross-country analysis

A decomposition of aggregate labor productivity based on internationally comparable data reveals that a high share of employment and low labor productivity in agriculture are mainly responsible for low aggregate productivity in poor countries. Using a two-sector general-equilibrium model, we show that differences in economy-wide productivity, barriers to modern intermediate inputs in agriculture, and barriers in the labor market generate large cross-country differences in the share of employment and labor productivity in agriculture. The model implies a factor difference of 10.8 in aggregate labor productivity between the richest and the poorest 5% of the countries in the world, leaving the unexplained factor at 3.2. Overall, this two-sector framework performs much better than a single-sector growth model in explaining observed differences in international productivity.     

Scenario-based approach in dealing with climate change impacts in Central Tanzania

Climate variability and change continue to be a threat to Africa’s agro-ecosystems. This is anticipated to have a multitude of immediate and long-term impacts on sub-Saharan Africa’s natural resources of the present study attempts to establish the potential benefit of integrating local stakeholders’ knowledge into climate scenarios. Specifically, the study sought to tap into the expertise and perspectives of locally important stakeholders in the potentially sensitive Wami/Ruvu River catchment of Tanzania. Participatory scenario planning was used to explore sectors sensitive to climate variability and change. This included 84 selected smallholder farmers and their leaders spread across six villages within the catchment. Quantitative household surveys were conducted across 199 households and Supplementary information sourced from regional statistics. The survey indicates that farmers project that land and agricultural productivity and water resources will be affected by climate change. From the participatory approach adopted for the study, thematic scenario categories featuring land and water resource-use and management and farm productivity were developed. The research found scenario analysis as a useful tool in development planning, as it incorporates interacting risks and uncertainties. If adopted by local farmers, leaders, regional institutional frameworks and policy makers, the tool has the potential to improve responsiveness to changes and risks through its collaborative management approach. This study demonstrates the need for sustainable water use and management systems and land use and farming practices that will increase crop productivity and resilience to climate variability and change.     

Firm Size and National Profiles of IFRS Policy Choice

Previous research on the International Financial Reporting Standards (IFRS) policy choices of large listed companies found a very strong association between policy choice and country. Nationally based pre‐IFRS practices largely explain IFRS policy choices. Nevertheless, some of the policy choices appear to be influenced from abroad, perhaps chosen in order to increase comparability. It has been suggested that smaller companies might be less influenced from abroad, and therefore might display even clearer national profiles of IFRS practice. This paper examines the accounting policy choices made within IFRS financial statements by small listed companies in five major countries. We find highly significant differences between the policies of small and large companies. We also find that small companies make more homogeneous choices, within a country, than large companies do. As a result, the previously published national profiles of the IFRS practices of large companies are misleading in the context of smaller ones.     

A structural decomposition of the U.S. trade balance: Productivity, demographics and fiscal policy

The US external deficits have been the most striking manifestation of global imbalances. This paper investigates the contribution of productivity growth, demographics and fiscal policy in accounting for the evolution of the US external imbalances against industrialized countries during the last three decades. Productivity growth plays a dominant role. Demographics explain a non-negligible and nearly permanent component of the US trade deficit. Furthermore, the international demographic transition is crucial for large US external imbalances to be consistent with the persistent decline of world real interest rates observed in the data. Fiscal policy is of minor importance.     

Euro area external imbalances and the burden of adjustment

The objective of this paper is to explore the consequences of the correction of Euro area trade imbalances on real exchange rates. This analysis requires one additional dimension with respect to the standard Global Imbalances framework à la Obstfeld and Rogoff (2005), since the adjustment takes place within and outside the Euro area. Both types of adjustments are analyzed in a three-country general equilibrium model with a tradable and a non-tradable sectors, and heterogeneous firms built upon Pappadà (2011). ECB (CompNet) data are used to measure the differences in firm size and productivity dispersion across Euro area countries. With respect to the surplus country (Germany), countries running a trade deficit (Spain, Italy) are characterised by a productivity distribution with a lower mean and a less fat right tail. This increases the relative price movement associated with the external adjustment because of the limited role played by the extensive margin. We show that the real exchange rate movements are underestimated when the cross-country differences in terms of productivity distributions are neglected.     

China's Abolition of the Agricultural Tax,Local Governments’ Responses and Economic Growth

When evaluating agricultural policy changes, much of the attention in the literature has been limited to agricultural productivity growth. This study demonstrates that, under a regionally decentralised authority system, the effect of China's abolition of the agricultural tax (AAT) in 2004–05 extended beyond the realm of agriculture. We find that, following the AAT reform, Chinese counties with higher reliance on agricultural taxation for budgetary revenue prior to the AAT reform experienced higher agricultural economic growth, as expected, but lower non‐agricultural economic growth in the short run. This growth‐inhibiting effect of the AAT reform on non‐agricultural production in the short run can be explained, to some extent, by the increased non‐agricultural taxation due to the insufficient funds that Chinese county governments received from the upper‐level governments following the AAT reform; the magnitude of this tax increase was associated with the degree to which each county relied on agricultural taxation for budgetary revenue prior to the reform. In addition, our results show that the AAT reform resulted in a high level of regional inequality in terms of non‐agricultural GDP per capita. In summary, our study shows that although the AAT reform succeeded in promoting agricultural production, such accomplishments were achieved at the cost of lower non‐agricultural output growth and higher regional inequality of non‐agricultural GDP per capita at the county level.     

Effects of Private Ownership,Trade, and Foreign Direct Investment on Labor Productivity Growth in Transition Economies: Evidence from the Croatian Manufacturing Industry

In this study, we investigate the determinants of labor productivity dynamics in transition economies using data from Croatian manufacturing industries. Capital intensity growth and human capital accumulation have been significant contributors to stronger productivity gains. Private-sector development has positively affected productivity growth—but mostly through the increasing role of new private companies. Still, unfinished privatization represents a significant obstacle to stronger productivity gains. The effect of increasing trade openness is significant but negative, most likely owing to weak export competitiveness of Croatian companies. Neither greenfield nor (predominant) brownfield foreign direct investment inflows have contributed to higher labor productivity growth. Further privatization and structural reforms seem to be the most promising policy measures that need to be undertaken in order to achieve higher productivity gains.     

What drives the disappearing dividends phenomenon?

We study the determinants of dividend payout policy and examine the role of liquidity, risk and catering in explaining the changes in propensity to pay. Our results indicate that risk plays a major role in firms’ dividend policy. The evidence substantiates from a large sample of firms representing 18 countries over the sample period from 1989 to 2011. For firms in the US, France, UK and Other European markets, liquidity is additionally an important determinant of dividend policy. We find that, although catering incentives persist only among firms in common law countries and not in civil law countries, after adjusting for risk there is little support for catering theory even among firms incorporated in common law countries. Our results indicate that catering incentives reflect the risk-reward relationship in the changing propensity to pay dividends.     

Cyclical fiscal policy,credit constraints,and industry growth

What are the effects of cyclical fiscal policy on industry growth? We show that industries with a relatively heavier reliance on external finance or lower asset tangibility tend to grow faster (in terms of both value added and of labor productivity growth) in countries that implement fiscal policies that are more countercyclical. We reach this conclusion using Rajan and Zingales׳s (1998) difference-in-difference methodology on a panel data sample of manufacturing industries across 15 OECD countries over the period 1980–2005.     

Productivity differences and the dynamic effects of labor movements

Barriers to labor mobility across countries coexist with substantial differences in living standards largely attributable to productivity differences. A growth model with endogenous labor movements is used to assess the effects on output, capital accumulation and welfare of removing barriers to labor mobility. The model is parameterized so that it is consistent with evidence on historical labor movements, and is applied to two cases: the enlargement of the European Union and the (hypothetical) creation of a common labor market in the North America. The main finding is that there are large resulting gains in terms of output and welfare.     

Payout policy and cash-flow uncertainty

The importance of cash-flow uncertainty in payout policy has received little attention in empirical studies, while survey studies such as [Lintner, J., 1956. Distribution of incomes of operations among dividends, retained earnings, and taxes. American Economic Review 46, 97–113.] and [Brav, A., Graham, J., Harvey C., Michaely, R., 2005. Payout policy in the 21st century. Journal of Financial Economics 77, 483–527.] indicate its importance. With worldwide firm-level data, we present evidence that cash-flow uncertainty is an important cross-sectional determinant of corporate payout policy. Our results show that across countries, cash-flow uncertainty, as proxied by stock return volatility, has a negative impact on the amount of dividends as well as the probability of paying dividends. The impact of cash-flow uncertainty on dividends is generally stronger than the impact of other potential determinants of payout policy—such as the earned/contributed capital mix, agency conflicts, and investment opportunities. We also find that the effect of cash-flow uncertainty on dividends is distinct from the effect of a firm's financial life-cycle stage.     

How International Exchange, Technology, and Institutions Affect Workers: An Introduction

In a world of deepening trade links, rapid technological change,and weakening institutions, workers in rich and poor countriesalike are concerned about their incomes and the security oftheir work. In contrast to the substantial quantity of analysison industrial countries, relatively little careful work hasbeen done on these issues in developing countries, especiallyin the context of the recent globalization of economic relations.Empirical work suggests that disequalizing trends in some developingcountries may have been caused by the entry of low-income countriessuch as China into world production or by the greater qualityand technological requirements of contemporary trade in goods.Whatever the source, these results raise questions about theviability of institutional mechanisms for supporting the incomesecurity and working conditions of workers. Many labor marketregulations are already ineffective owing to weak enforcementcapabilities. However, in most developing countries, there willbe a rising fraction of workers in formal labor contracts, risingdemands for formal mechanisms for dealing with income insecurity,and a potentially larger role for unions in an important segmentof the work force. Thus, it is of increasing importance to setthe policy and institutional framework in a fashion that isboth consistent with competitive pressures and supportive ofworkers' participation and security.
