Why are tax revenues of local governments so low?

Using a unique data set on federal grants and tax revenues of more than 5000 Brazilian cities, we find that the federal government imposes an implicit tax of almost 10% on city governments’ tax revenues: for every dollar that a city collects from its residents, the federal government withdraws grants worth 9 cents from the city. Our findings suggest that local government tax revenues are low not because federal grants crowd out tax revenues, but because tax revenues crowd out federal grants.     

Why are Latin America's savings rates so low? An international comparative analysis

This paper presents a theoretical and empirical assessment of the determinants of savings rates, with special emphasis on Latin American savings rates. The study is based on international comparisons, using data from 36 countries for 1970–1992. A distinction is made between private and public savings. The later are endogenously determined by economic and political variables. Per capita income growth is the most important determinant of private and public savings; public savings are lower in countries with higher political instability; public savings crowd out private savings, but less than proportionately. Low Latin American savings are due to the magnitudes of their determinants, rather than structural differences.     

Does productivity growth lower inflation in Korea?

We investigate Granger causality between productivity growth and inflation in Korea using quarterly data for the period 1985Q1–2002Q4. Our results indicate unidirectional Granger causality from productivity growth to inflation. In light of such causality, we estimate the effect of productivity and other variables on productivity. According to our regression results, a 1% increase in labour and Total Factor Productivity (TFP) reduces Consumer Price Index (CPI) inflation by 0.07–0.08% and 0.37–0.44%, respectively. Our results also suggest that the productivity-inflation nexus became stronger in Korea since the Asian financial crisis, and that this was largely due to structural reform and technological progress.     

Do process innovations boost SMEs productivity growth?

In this paper, we explore in depth the effect of process innovations on total factor productivity growth for small and medium enterprises (SMEs), taking into account the potential endogeneity problem that may be caused by self-selection into these activities. First, we analyse whether the ex-ante most productive SMEs are those that start introducing process innovations; then, we test whether process innovations boost SMEs productivity growth using matching techniques to control for the possibility that selection into introducing process innovations may not be a random process. We use a sample of Spanish manufacturing SMEs for the period 1991–2002, drawn from the Encuesta sobre Estrategias Empresariales. Our results show that the introduction of process innovations yields an extra productivity growth, and that the life span of this extra productivity growth lasts for only one period.     

Why Are There so Many Banking Crises?

The last 25 years have seen an impressive number of bankingcrises all over the world. These crises have renewed interestof economic research on the causes of fragility of banks andthe possible remedies to it. The justifications and organisationof public intervention in the banking sector have also beenput into question. This article builds on this recent researchin order to understand better the causes of banking crises andoffer policy guidelines for reform of regulatory and supervisorysystems. The main conclusions are: •Although many banking crises have been initiated by financialderegulation and globalization, these crises were largely amplifiedby political interference. •Supervision systems face a fundamental commitment problem,analogous to the time consistency problem confronted by monetarypolicy. •The key to successful reform is independence and accountabilityof banking supervisors.

Why are Trade Agreements Regional?

This paper shows how distance may be used to coordinate on a unique equilibrium in which trade agreements are regional. Trade agreement formation is modeled as coalition formation. In a standard trade model with no distance between countries a familiar problem of coordination failure occurs, giving rise to multiple equilibria; any one of many possible trade agreements can form. With distance between countries, regional trade agreements generate larger rent‐shifting effects than nonregional agreements. Countries use these effects to coordinate on a unique equilibrium.     

Why is TFP growth sectorally concentrated?

Research shows that total factor productivity (TFP) growth is weak in European countries. This is inter alia attributed to the fact that substantial TFP growth is limited to a few industries. Because TFP growth is typically understood as technological progress, it is concluded that technology diffusion between sectors in Europe is hampered. We use EU KLEMS data sets to decompose sectoral TFP for nine European countries by means of a Malmquist approach in order to identify potential sources besides technical progress. Applying Harberger diagrams, we describe the sectoral distribution of TFP growth, efficiency gains and losses, economies of scale and technological progress. The analysis reveals that technological progress is quite evenly distributed across sectors in most European countries. The wide scattering of TFP growth is explained by deviating efficiency developments and the unused economies of scale. We conclude that the technology transfer between sectors in most European countries seems to work. Therefore, Europe in general does not need a new technology policy, but a further integration of the markets and a reduction of national market entry barriers. This requires further unification of pan-European standards in fields like trade and crafts codes or consumer protection policies.     

Why did the terms of payment in international trade change so much?

This article examines factors contributing to the substantial change in the terms of payment, such as letter of credit (LC) and cash terms, in Korean export transactions during the period 1997–2015, using the Autoregressive Distributed Lag bounds test approach. We find that high competition in the world market, the expansion of exports of information technology products and intra-firm trade, and the improvement of information and communication technology (ICT) decrease the share of exports on LC terms in total exports in the long run. However, the increase in exports to developing countries raises the use of LC terms. On the other hand, the increase in intra-firm trade and ICT improvement raise the share of exports settled in cash, and higher trust between trading partners increases the use of cash terms.     

What are the drivers of total factor productivity in the European Union?

This paper examines the evolution of total factor productivity (TFP) over time, as well as across countries and sectors, and investigates its determinants. To this end, a panel data set of 17 European Union (EU) countries and 13 sectors over the period 1995–2007 is used as part of a twofold approach. First, we estimate aggregate and sectoral TFP for 17 EU countries by means of the augmented mean group estimator to control for endogeneity, cross-section dependence and heterogeneous production technologies. Second, we investigate the relative importance of the drivers of predicted TFP using a dynamic ordinary least-squares estimator. The results indicate that rationalization, human capital and information and communication technologies are the main drivers of TFP.     

Why are profits correlated with concentration?

In a free-entry non-cooperative oligopoly a correlation between profitability and concentration arises from the indivisibility of firms. Although a ‘perverse’ negative correlation is possible, most distributions of entry fees across industries yield a positive correlation.     

The management function of entrepreneurs and countries’ productivity growth

This article examines the determinants of the equilibrium number of entrepreneurs and the level of productivity in economies where individuals make occupational choices between being self-employed or working as an employee. The results of the theoretical model explain some observed empirical regularities, such as the negative association between productivity and self-employment rates in cross-country data. The article also derives and empirically tests an unexplored relationship between entrepreneurship and economic growth, in the form of a positive association between productivity growth in t and the proportion of the self-employed in t???1, providing a new perspective on cross-country productivity convergence over time.     

Why are shortages of hospital RNs concentrated in specialty care units?

This article is the first in a series examining the interplay between the aging of the nurse workforce and other factors driving the growing nursing shortage that are already affecting some specialty areas. Nearly 60% of the current RN workforce is over 40 years of age; and the percentage of RNs under age 30 has fallen by nearly 40% since 1980. The total number of FTE RNs is projected to shrink after 2010, likely resulting in shortages of RNs "when the large baby-boom generation of RNs starts to retire." Because ICUs have historically attracted younger RNs, the rapid decline in the number of RNs in the workforce under age 30 plays a large role in explaining the development of shortages in the ICU. The growing difficulties staffing operating rooms and other peri-operative services is seen as related to the aging work force as more diploma prepared nurses have been attracted to this specialty because they had educational exposure to this area.     

What is the optimal rate of R&D investment to maximize productivity growth?

Governments in modern economies devote much policy attention to enhancing productivity and continue to emphasize its drivers such as investment in R&D. This paper analyzes the relationship between productivity growth and levels of R&D investments. The econometric analysis shows that more than 65 per cent of productivity growth variance is due to its dependence on gross domestic expenditure on R&D expressed as percentage of GDP (GERD). Economic analysis shows that productivity growth = f(GERD) is a concave function downwards due to diminishing returns to research investments. In addition, the research shows that the range of GERD between 2.3 per cent and 2.6 per cent maximizes the long-run impact on productivity growth and it is the key to sustained productivity and technology improvements that are becoming more and more necessary to modern economic growth.     

Why is education performance so different across Latvian schools?

This paper aims to identify the school characteristics consistently associated with better performance of pupils in state exams in Latvia and understand the reasons behind substantial exam score gap between urban and rural schools. We find that exam scores are positively related to school size and teacher salaries, but negatively related to teacher age. Oaxaca–Ransom decomposition shows that the whole urban–rural exam score gap can be attributed to a few observable characteristics of schools, teachers and pupils.     

How important are dual economy effects for aggregate productivity?

This paper brings together development accounting techniques and the dual economy model to address the role that factor markets have in creating variation in aggregate total factor productivity (TFP). Development accounting research has shown that much of the variation in income across countries can be attributed to differences in TFP. The dual economy model suggests that aggregate productivity is depressed by having too many factors allocated to low productivity work in agriculture. Data show large differences in marginal products of similar factors within many developing countries, offering prima facie evidence of this misallocation. Using a simple two-sector decomposition of the economy, this article estimates the role of these misallocations in accounting for the cross-country income distribution. A key contribution is the ability to bring sector-specific data on human and physical capital stocks to the analysis. Variation across countries in the degree of misallocation is shown to account for 30–40% of the variation in income per capita, and up to 80% of the variation in aggregate TFP.     

Why some product innovations are licensed and others are not?

We study in a Stackelberg industry the licensing of a product that embodies an innovation (quality-improving product) whose owner may be the firm that plays as a leader or a follower in setting output in the the product market. We find that the innovation is transferred (and social welfare is reduced) if its owner is the market-leader firm. However, if the innovation is in the hands of the market-follower firm, it is not licensed, even though licensing would be welfare enhancing. Thus, subsidizing R&D with the mandatory licensing of the resulting innovation may be a socially desirable policy.     

Does federally financed business R&D matter for US productivity growth?

This paper investigates the impact of federally financed business R&D on productivity of the US nonfarm business sector. Results of a cointegration analysis suggest that a long run relation between productivity and total (privately and federally financed) R&D capital stock exists. Moreover, the estimation results do not confirm the finding of previous empirical studies that the productivity effects of federally financed business R&D are lower compared with those of privately financed business R&D.     

Corruption and total factor productivity: level or growth effects?

This paper adopts a productivity-based perspective in order to study how corruption conditions the efficiency levels of the economies and their TFP growth rate. It attempts to identify the channels through which corruption can influence productivity growth, whether by conditioning improvements in relative efficiency levels or by shifting the production frontier. The results point out that corruption negatively affects both the levels of efficiency at which the economies perform and the growth rate of TFP, suggesting that the negative impact of corruption on technological progress manifest through its influence on human capital.     

Can total factor productivity explain value added growth in services?

This paper examines the factors responsible for generating the services led growth witnessed in the Indian economy during 1980–2005. A sectoral growth accounting exercise shows that total factor productivity (TFP) growth was the fastest for services; moreover this TFP increase was significant in accounting for service sector value added growth. A growth model with agriculture, industry and services as three principal sectors is calibrated to Indian data using sectoral TFP growth rates. The baseline model performs well in accounting for the evolution of value added shares and their growth rates, but is unable to capture sectoral employment share trends. The performance of the model with respect to value added shares improves when the post 1991 increase in service sector TFP growth following the inception of market-based liberalization reforms is accounted for. A modified version of the model with public capital can better track trends in sectoral employment shares.
