The relationship between inequality and innovative activity: a Schumpeterian theory and evidence from cross‐country data

This article examines the effect of inequality on technological progress when innovations are protected by patents of finite length. It provides a Schumpeterian theory of the non‐linear relationship between income distribution and innovative activity in a dynamic general equilibrium setting. Additionally, the theory is empirically tested by investigating how inequality affects innovative activities in a cross‐country setting. Using two new data sets on inequality, one linear and two non‐linear dynamic panel data models are estimated. The results are robust to two common inequality measures. They support the hypothesis that there is an overall negative relationship between inequality and innovative activity and the relationship is non‐linear but not necessarily an inverted‐U.     

Peaks vs Components

We analyze the cross‐national distribution of gross domestic product (GDP) per capita and its evolution from 1970 to 2009. We argue that peaks are not a suitable measure for distinct convergence clubs/equilibria in the cross‐country distribution of GDP per capita, because the number of peaks is not invariant under non‐linear strictly monotonic transformations of the data such as the logarithmic transformation. Instead, we model the distribution as a finite mixture, and determine its number of components via statistical testing. We find that the number of components in the cross‐country distribution changes from three to two in the mid 1990s.     

How Does Foreign Direct Investment Really Affect Developing Countries' Growth?

Two main contributions to literature on foreign direct investment (FDI) and economic growth are made in this paper. First, the paper examines the effect of FDI on economic growth for 44 developing countries using heterogeneous panel cointegration techniques that are robust to omitted variables and endogenous regressors. The main result is that FDI has, on average, a negative effect on growth in developing countries, but there are large differences in the effect across countries. Second, a general‐to‐specific model‐selection approach is used to systematically search for country‐specific factors explaining the cross‐country differences in the growth effects of FDI. The results suggest that the cross‐country heterogeneity in the growth effect of FDI can be explained mainly by cross‐country differences in freedom from government intervention, business freedom, FDI volatility, and primary export dependence.     

MFN vs Tariff Discrimination in the Presence of Cross Ownership

We develop a three‐country two‐firm model to examine the superiority of most favored nation (MFN) vs tariff discrimination in global welfare by taking into account the cross ownership between exporters. We obtain several interesting results as follows. First, given cross ownership of financial interests and linear demand, the government of the importing country will impose a lower (higher) tariff on the low‐cost (high‐cost) firm and the global welfare under tariff discrimination will be higher than that under MFN, regardless of whether the mode of competition is Cournot or Bertrand competition, when the magnitude of cross ownership is relatively large compared with the cost difference. Second, given the cross ownership of corporate control and linear demand, the global welfare under tariff discrimination will be identical to that under MFN.     

ROLLING REGRESSION VERSUS TIME‐VARYING COEFFICIENT MODELLING: AN EMPIRICAL INVESTIGATION OF THE OKUN'S LAW IN SOME EURO AREA COUNTRIES

During the last decade, economists have shown that the inverse relationship between economic growth and unemployment rate varies over time. Rolling regression has been the main tool used to quantify such a relationship. This methodology suffers from several well‐known problems which lead to spurious non‐linear patterns in the Okun's coefficient behaviour over time. Here, we take a penalized regression spline approach to estimate the Okun's time‐varying effects. As a result, spurious non‐linearities are suppressed and hence important time‐varying coefficient features revealed. Our empirical results show that the inverse relationship in some Euro area countries is spatially heterogeneous and time‐varying. The findings are complemented by the calculation of the rate of output growth needed for a stable unemployment rate, as proposed by Knotek.     

DEFENCE AND NON‐DEFENCE SPENDING IN THE USA: STIMULI TO ECONOMIC GROWTH? COMPARATIVE FINDINGS FROM A SEMIPARAMETRIC APPROACH

Given its significant policy implications, the nexus between public expenditures and economic growth has been the subject of an extensive and often emotive theoretical and empirical debate. In this paper, a semiparametric model is used to explore the link between GDP and defence and non‐defence government spending in the USA over the period 1929–2009. Evidence reported herein indicates that the latter represents a greater stimulus vis‐à‐vis the former.     

The non‐monotonic relationship between seigniorage and inequality

Abstract. We present an analysis of how political factors may come into play in the equilibrium determination of inflation. We employ a standard overlapping generations model with heterogenous young‐age endowments, and a government that funds an exogenous spending via a combination of non‐distortionary income taxes and the inflation tax. Agents have access to two stores of value: fiat money and an inflation‐shielded, yet costly, asset. The model predicts that the relationship between elected reliance on the inflation tax (for revenue) and income inequality may be non‐monotonic. We find robust empirical backing for this hypothesis from a cross‐section of countries. JEL classification: E5, P16     

COSTLY INTERMEDIATION AND THE POVERTY OF NATIONS*

This article has two goals: (i) to reduce the 7‐fold productivity differential required to explain the observed 33‐fold income difference between the richest and poorest countries of the world; and (ii) to explain cross‐country differences in the capital‐output ratio. To achieve the first goal we modify the production function of the standard neoclassical growth model to include public capital whose provision is subject to intermediation costs. For the second goal we distort private investment by introducing credit frictions. The model, quantified using cross‐country data, generates an income gap of 33 with productivity differences of only 3 under the measured variations in public and private capital. The required productivity gap declines even further, to 2.1, when we introduce a home‐production sector. On the second goal, however, credit frictions do a poor job of explaining cross‐country variations in the capital‐output ratio.     

A REVISIT TO THE STATIONARITY OF OECD INFLATION: EVIDENCE FROM PANEL UNIT‐ROOT TESTS AND THE COVARIATE POINT OPTIMAL TEST*

This paper re‐examines the stationarity of inflation rates in 19 Organisation for Economic Cooperation and Development countries with the use of cross‐sectional information. We employ the panel unit‐root tests that allow for cross‐sectional dependency and the covariate point optimal test. These tests have high power in common due to the exploitation of cross‐sectional information, and they can assist mutually to draw a concrete conclusion on inflation dynamics for all series in the panel. Our empirical results show that allowing for cross‐sectional dependency rejects the null hypothesis that all series in the panel have a unit root, implying that there is at least one stationary series in the panel. With the help of the results of the covariate test, we can distinguish the panel into a group of stationary and a group of non‐stationary series. For robustness, the two groups of series are re‐confirmed by the panel tests. Our results reveal evidence of mean reversion in inflation for 15 of 19 countries, which is significantly stronger as compared to that obtained by the state‐of‐the‐art univariate unit‐root tests.     

Resource Curse or Not: A Question of Appropriability*

Whether natural resources are good or bad for a country's development are shown to depend on the interaction between institutional setting and, crucially, the types of resources possessed by the country. Some natural resources are, for economical and technical reasons, more likely to cause problems such as rent‐seeking and conflicts than others. This potential problem can, however, be countered by good institutional quality. In contrast to the traditional resource curse hypothesis, we show the impact of natural resources on economic growth to be non‐monotonic in institutional quality, and increasingly so for certain types of resources. In particular, countries rich in minerals are cursed only if they have low‐quality institutions, while the curse is reversed if institutions are sufficiently good. Furthermore, if countries are rich in diamonds and precious metals, these effects—both positive and negative—are larger.     

Does Taxation Stifle Corporate Investment? Firm‐Level Evidence from ASEAN Countries

This article conducts a firm‐level analysis of the effect of taxation on corporate investment, using large‐scale panel data on non‐financial firms over the period 1990–2014, and controlling for macrostructural differences among ASEAN countries. We find a significant degree of persistence in fixed investment over time, which varies with firm characteristics, such as size, growth prospects, profitability and leverage. The non‐linear estimations indicate that taxation facilitates business investment (possibly by enabling public investment in infrastructure and human capital, and the proper functioning of government institutions), but this effect turns negative and stifles private investment growth as the tax burden increases.     

ON THE EMERGENCE OF NON‐PROFIT FIRMS AS ALTERNATIVES TO THE GOVERNMENT*

It is well known that many non‐profit firms coexist with government firms in industries that provide collectively consumed goods and services, such as education, healthcare, social services, and art and culture. This paper explores the specific circumstances under which non‐profit firms can emerge as alternatives to the government. We show that a non‐profit firm emerges only when the residents’ median preference for a collective good is significantly low. This finding implies that, somewhat paradoxically, a non‐profit firm emerges to replace the government and provide a collective good only when the majority of residents consider the good non‐essential.     

Trade,finance or policies: What drives the cross-border spill-over of business cycles?

In this paper we investigate how income growth rates in one country are affected by growth rates in partner countries, testing for the importance of pairwise country links as well as characteristics of the receiving country (trade and financial openness, exchange rate regime, fiscal variables). We find that trade integration fosters the spill-over of business cycles, both bilaterally and as a country characteristic (trade openness). Results for financial integration are mixed; financial links as pairwise country characteristic are either insignificant or negatively signed (indicating a dampening of cross country spill-overs), but financial openness as characteristic of the receiving country amplifies spill-overs. We find no evidence for a role of the exchange rate regime. Finally, we find that higher government spending and debt reduces countries’ vulnerability to foreign business cycles, presumably through the effect of automatic stabilizers.     

Leadership in Public Good Provision: A Timing Game Perspective

We address in this paper the issue of leadership when two governments provide public goods to their constituencies with cross‐border externalities as both public goods are valued by consumers in both countries. We study a timing game between two different countries: before providing public goods, the two policymakers non‐cooperatively decide their preferred sequence of moves. We establish conditions under which a first‐ or second‐mover advantage emerges for each country, highlighting the role of spillovers and the complementarity or substitutability of public goods. As a result, we are able to prove that there is no leader when, for both countries, public goods are substitutable. When public goods are complements for both countries, each of them may emerge as the leader in the game. Hence a coordination issue arises. We use the notion of risk‐dominance to select the leading government. Finally, in the mixed case, the government for whom public goods are substitutable becomes the leader.     

Does public‐sector employment fully crowd out private‐sector employment?

Employment matters for development because it can raise household income, lower inequality, promote economic growth, and contribute to political stability. Many countries have high rates of public employment, but what effect does this have on overall employment and unemployment rates? This paper investigates if and to what extent public‐sector employment crowds out (reduces) private‐sector employment. In particular, we estimate regressions of unemployment or private‐sector employment on two measures of public‐sector employment. The study uses an especially assembled dataset, which is novel for its coverage of a large sample of developing countries as part of a panel of rich and poor countries. Our results point to full or just about full crowding‐out for the entire sample. Unlike previous cross‐country studies, which were restricted to advanced economies, we are able to show that these results also apply to developing countries, although crowding‐out may not be quite as high as in advanced economies. The results mean that high rates of public employment have an offsetting large negative impact on private employment rates and do not reduce overall unemployment rates. With the qualifier that government activities may help the economy in other ways, our results imply that, rather than creating public‐sector jobs, scarce fiscal resources could be better spent on other developmental needs.     

FURTHER EVIDENCE ON REAL INTEREST RATE EQUALIZATION: PANEL INFORMATION,NON‐LINEARITIES AND STRUCTURAL CHANGES

Previous studies applying traditional unit root tests generally have difficulty providing widespread evidence supporting the real interest rate parity hypothesis (RIPH). This paper aims to analyse the empirical fulfilment of RIPH for 17 OECD countries by employing many recently developed unit root tests. Power of the tests is raised by taking different approaches, such as using cross‐sectional information, accounting for non‐linear adjustment towards the equilibrium and allowing for structural changes. The combined results of the tests using panel information show that broad evidence in favour of RIPH prevails for 13 of the 17 countries. By contrast, univariate tests fail to make widespread rejections of the unit‐root hypothesis. Our evidence reveals a high degree of market integration for developed countries, and the effect of monetary policies as a stabilization tool might be limited at least in the long run.     

技术选择、技术扩散与经济收敛

Lin(1994,1996a,b,1999,2001)的技术选择假说认为一个国家的经济结构是由其要素禀赋结构内生决定的.一个发展中国家政府所采取的发展战略如背离了最优的技术选择将影响该国的经济增长速度及是否能够向发达国家的收入水平收敛.本文构建了一个增长函数,除技术选择外,还同时考虑地理位置、政府质量等因素在长期内对各国全要素生产率(TFP)的影响.我们用跨国数据对该模型进行估计,检验影响长期TFP差异的各种假说,结果支持Lin的技术选择假说、Sachs et al.(1995,1999)的地理位置假说,但结果未支持政府质量假说.     

RUSSIAN LIVING STANDARDS DURING THE INDUSTRIALIZATION ERA, 1885–1913*

In this paper, I have examined the relative growth rates of personal consumption, government consumption, and national income in Russia from 1885–1913 and have contrasted them with the “European” model (derived from the U.K. and German experience). Two hypotheses of the conventional model of Russian industrialization were tested: the retarded growth of personal consumption and the accelerated growth of government consumption and investment (relative to the European model) and the growing Europeanization of Russian growth after 1906. The estimates of personal consumption and government consumption failed to sustain either hypothesis. In fact, the reverse hypotheses appear to be more plausible. The lack of data on investment prevented the testing of the investment hypothesis, but the limited evidence which is available does not point to an extraordinary growth of investment. As a final experiment, the combined growth rates of personal and government consumption were compared with a revision of Goldsmith's national income estimates. They were shown to provide strong support for the accuracy of the revision of Goldsmith's estimates.     

THE SCOPE FOR NON‐PROFIT OBJECTIVES IN A MIXED OLIGOPOLY UNDER INTERNATIONAL COMPETITION

We ask how the scope for non‐profit objectives in a state‐owned enterprise (SOE) in a mixed oligopoly changes because of competition from firms in another country. There is no change if costs and demand are given, unless the trade partner is a low‐cost country. However, the scope for non‐profit objectives is limited by the country's relative size if wages are market‐clearing and if workers and firms are stationary, because of reduced competitiveness caused by higher real wage rates. The total surplus is then not affected by the actions of the SOE. International trade does not otherwise reduce the scope for its non‐profit objectives if workers and firms are mobile, but productivity differences might require restrictions in order to avoid a complete relocation of the workforce in either country.     

Growth and Election Outcomes in a Developing Country

We offer the first test of the hypothesis that rapid growth helps incumbents win elections for a developing country, India. We generalize the Fair (1978) model to allow for multiple candidates and test it using cross‐state data on 422 candidates in the 2009 parliamentary elections. We find quantitatively large and statistically robust effect of growth on the prospects of the candidates of the state incumbent parties to win elections.
