Location matters: Estimating cluster premiums for prominent modern artists

This paper shows that ‘location matters’ in terms of premiums on creative clusters and peak ages. The analysis is based on the 214 most prominent modern visual artists born 1850-1945 and the art clusters of Paris and New York. Auction records of the past 20 years are used to estimate the value of artworks over an artist's career. The overall cluster premium for paintings produced in Paris and New York is found to be 11% and 43%, respectively; paintings made in Paris during the First World War have a premium of 14% while those produced between 1946 and 1975 have a premium of 27%. New York offers premiums for paintings produced there for all periods after the First World War, peaking at 74% between 1946 and 1975. When decomposing this premium, we find that quality rather than quantity of artists in the location is driving the results. It is argued that artists working in a cluster location reach a peak in the age-price profile of their work significantly earlier than artists working elsewhere.     

A tale of two states: asymmetries in the UK small,value and momentum premiums

This article performs comparative analysis of the asymmetries in size, value and momentum premium and their macroeconomic determinants over the UK economic cycles, using Markov switching approach. We associate Markov switching regime 1 with economic upturn and regime 2 with economic downturn. We find clear evidence of cyclical variations in the three premiums, most notable being that in the size premium, which changes from positive in expansions to negative in recessions. Macroeconomic indicators prompting such cyclicality the most are variables that proxy credit market conditions, namely the interest rates, term structure and credit spread. Overall, macro factors tend to have more significant impact on the three premiums during economic downturns. The results are robust to the choice of information variable used in modelling transition probabilities of the two-stage Markov switching model. We show that exploiting cyclicality in premiums proves particularly profitable for portfolios featuring small cap stocks in recessions at a feasible level of transaction costs.     

Environmental regulations,induced R&D,and productivity: Evidence from Taiwan's manufacturing industries

This paper examines whether stringent environmental regulations induce more R&D and promote further productivity in Taiwan. Using an industry-level panel dataset for the 1997–2003 period, empirical results show that pollution abatement fees, a proxy for environmental regulations, is positively related to R&D expenditure, implying that stronger environment protection induces more R&D. On the other hand, pollution abatement capital expenditures do not have a statistically significant influence on R&D. Further evaluation of the influence of induced R&D by environment regulations on industrial productivity shows a significant positive association between them. This finding supports the Porter hypothesis that more stringent environmental regulations may enhance rather than lower industrial competitiveness.     

Are U.S. growth and value stocks similarly integrated with the world markets? A test across business cycles

Utilizing the bivariate GARCH-in-mean methodology, this study examines the strength of global risk premia using 10 major foreign stock markets with two style-based, large-cap U.S. index funds and S&P500, for the period 1993–2014. We incorporated seven U.S. business cycles. The foreign risk premium was found to be significantly strong for both growth and value stocks, and the S&P500 index, indicating that U.S. integration within global market is strong and persistent over the past 20 years. We report distinct risk characteristics owing to global linkages, for the two style-based U.S. funds over different business cycles. The foreign risk premium for growth stocks is mostly positive and especially high during contractions; in contrast, the value stocks demand more premiums during expansions. The growth and value linkages with foreign countries also vary quite substantially over the business cycles. A possible sign of convergence is the decreasing difference between value and growth foreign risk premiums, post-2001, perhaps indicative of greater domestic and global market integration. Our results support a solid, continuing trend of U.S. integration within global markets, with an influential role of business cycles.     

Could immigration explain wage inequality in a skill-biased technological model?

The aim of this paper is to evaluate how immigration of high-skilled workers affects the technological-knowledge bias and, in turn, the skill premium in the host countries, in particular bearing in mind the recent experience in a number of European countries. We study a skill-biased dynamic general equilibrium R&D growth model in which the standard R&D technology is modified so wage inequality results from the direction of the technological knowledge, which in turn is induced by the price channel. By solving the transitional dynamics numerically, we show that the rise of the skill premium arises from the price-channel effect, complemented with a mechanism that reflects the impact of immigration on R&D. According to our quantitative results, our model is able to account for a significant proportion of the dynamics of the skill premium in the data for a number of European countries, thus, suggesting that differences in labour skills between immigrants and natives are, in practice, an important source of skill premium variation over time.     

Do financial distress and liquidity crises affect value and size premiums?

This study investigates the impact of liquidity crises on the relationship between stock (value and size) premiums and default risk in the US market. It first examines whether financial distress can explain value and size premiums, and then, subsequently, aims to determine whether liquidity crises increase the risk of value and size premium investment strategies. The study employs a time-varying approach and a sample of US stock returns for the period between January 1982 and March 2011, a period which includes the current liquidity crisis, so as to examine the relationship between default risk, liquidity crises and value and size premiums. The findings indicate that the default premium has explanatory power for value and size premiums, which affect firms with different characteristics. We also find that liquidity crises may actually increase the risks related to size and value premium strategies.     

Bad volatility is not always bad: evidence from the commodity markets

ABSTRACT

Using exchange-traded fund (ETF) options data, we examine the predictive power of variance risk premium on returns of four commodities: crude oil, natural gas, gold and silver. We also analyze the predictive power of upside and downside variance risk premiums using a decomposition model conditional on the direction of the underlying market movement. We find that both the undecomposed and decomposed variance risk premiums are able to predict commodity prices. The decomposed variance risk premiums, however, outperform the undecomposed premium. The importance of upside and downside variance risk premiums differs across markets, related to hedging demand. In energy markets, both upside and downside premiums have strong predictive power, while in precious metal markets, only the upside premium is predictive.     

The impact of health sector on R&D,economic growth and wages

We extend the existing R&D growth literature by focusing on the short-, medium-, long-run effects of the health sector on R&D intensity, economic growth and wages, and by considering 21 OECD countries between 1991 and 2008. We show that: (i) there is a unique and stable steady state; (ii) an increase in health-labour share in skilled population has no effect on growth, but affects negatively (positively) the R&D intensity (the skill premium); (iii) Anglo–Saxons countries have the lowest health-labour share in skilled-labour population, and Nordic countries have the lowest skill premium and the highest consumption/production of healthcare per capita.     

Price transmission,foreign exchange rate risks and global diversification of ADRs

The purposes of this article are to reinvestigate how returns of major American depository receipts (ADRs) from different countries are related to the underlying stock returns and to identify the determinants of ADR risk premiums. We use different types of error-correcting terms in vector error correction models to examine information flows between ADRs and the underlying foreign stocks. General method of moments estimation of conditional international asset pricing model of Dumas and Solnik (1995 Dumas, B and Solnik, B. 1995. The world price of foreign exchange risk. Journal of Finance, 50: 445–79. [Crossref], [Web of Science ®] , [Google Scholar]) is applied to investigate ADR return premiums. We find that stock returns are more affected by disequilibrium between ADR and stock prices in an inefficient way. For US investors, foreign exchange rate risk premiums and world market risk premium (beyond US index) are priced in ADRs returns ex ante. Surprisingly, it is shown that the exchange rate of New Taiwan dollar and the interest rates of Brazil and Taiwan play important roles in determining ADR risk premiums across countries.     

Corporate governance structure,managerial discretion,and the R&D investment in China

This article studies the influence of corporate governance factors on firm R&D investment in a transitional economy like China. By using the data from the listed companies in China, this article statistically tests the hypotheses on the relations between corporate R&D intensity and managerial discretion of CEOs, independent outside directors, degree of share concentration, share held by the state, and share held by a manager. According to the results, the managerial discretion of CEOs has a significant and negative correlation with the firm R&D investment. The number of the independent outside directors in the board has a positive influence on the R&D investment. And as the shares held by a manager increase, the firm R&D intensity will decrease at first, and then increase along an inverted parabolic curve. All these findings show that the improvement of corporate governance and stock incentive plan, and the cultivation of active and long-term stock investors, may finally lead to the upgrade of corporate innovation capabilities.     

中国国情下的保险费率监管模式选择及影响分析--来自车险市场的经验证据

我国保险监管朝着“放开前端、管住后端”的模式发展,保险费率市场化改革的呼声始终较高。文章以财险市场中市场份额最大的车险为研究对象,基于2001－2014年样本分析了费率市场化与费率水平合理性之间的关系。研究发现,我国车险市场的实际费率水平明显低于理论费率;费率监管的严格程度的确会影响费率水平的合理性,其中适度监管模式下的费率水平最为合理。文章进一步深入探究了费率水平合理性对偿付能力的影响机制,发现费率差异的波动性会通过净利润而间接影响偿付能力。费率差异的波动性越小,净利润越高,偿付能力越强,因此应慎重选择费率监管制度。文章建议我国保险市场应采用适度监管的费率制度,完全放开的费率市场化略显激进,不适合当前国情。这样不仅能使费率水平更加合理,还不会威胁保险公司的偿付能力,从而使保险市场更加健康稳步的发展。     

HOW DO JAPANESE HEALTH INSURANCE SOCIETIES FINANCE THEIR CONTRIBUTIONS TO THE HEALTH SERVICE SYSTEMS FOR THE ELDERLY?*

We examine how Japanese health insurance societies finance (or distribute) the costs (or cost savings) from an increase (or decrease) in contributions to the Health Service Systems for the Elderly. Three ways are possible: (i) adjusting the premiums of the employee or employer; (ii) providing an optional benefit; and (iii) adjusting reserves by the change in contribution. We find that more than six‐sevenths of the changes are associated with changes in reserves, followed by premiums, and finally optional benefits. The increase in the premium mostly shifted to employees, while employees enjoyed a nearly 60% decrease in total premium.     

Asymmetric impacts of insurance premiums on the non-oil GDP: some new empirical evidence

ABSTRACT

In this paper, we study the influence of insurance premium on the non-oil gross domestic product in Saudi Arabia. We implement the nonlinear autoregressive distributed lags. The results show that the relationships between insurance premiums and non-oil gross domestic product manifest a nonlinear behaviour. In other words, insurance premiums via positive and negative shocks lead to an increase of growth in the non-oil sector in the long term, whereas the lagged level shocks negatively affect the non-oil GDP in the short run. In addition, the examination of the multiplier effect suggests that positive cumulative changes in insurance premiums and inflation can effect much larger changes in non-oil GDP, while shocks in government spending have a symmetric effect on non-oil GDP growth.     

Investment barriers and premiums on closed-end country funds

We investigate the cross-sectional relation between investment barriers and premiums on closed-end country funds (CECFs) traded in U.S. markets over the period from 1995 to 2004. We find that funds investing in markets with higher indirect investment barriers as measured by market turnover and country risk have higher premiums. We also document that the relation between the country risk and CECF premium is much stronger after the stock market liberalization. Since investors prefer to invest in emerging markets with high indirect barriers through country funds, they increase the premiums of the funds targeting those countries. In addition, we find that direct investment barriers as measured by the investable weight factor do not explain the large variation in the CECF premiums.

中国研发投入的动态演化

R&D investment is enterprises’ strategy based on the market demand on innovative products and its production capacity for them. Enlarging market demand would spur the enterprises’ R&D input and the enhancement of technology state in production ability could have a complex effect on less developed countries’ R&D expenditure. With the measurement of China’s technology state compared to the United States and Japan, this paper explores with the state space model the dynamic effects of determinants on China’s R&D expenditure with the data during 1987–2006. The result illustrates that the growing national income, a proxy of domestic market demand, impedes the further R&D investment in China due to the enormous demand for necessities dominated by lower income class, and the income inequality is the major incentive for R&D investment via the higher pricing on the wealthy group, and that the improvement of technology state reduces the innovation risk and plays an important role in stimulating R&D expenditure.      

Costly investment, complementarities and the skill premium

We propose a new framework to analyse the relationship between the relative high-skilled labour endowment, the skill premium and economic growth. Building on Acemoglu and Zilibotti (2001), we introduce physical capital; internal costly investment in both capital and R&D; and complementarities between intermediate goods. We only find a positive relationship between the relative labour endowment and both the skill premium and economic growth within determined intervals of relative labour endowment values, which vary with the absolute productive advantage of high over low-skilled labour. The model thus accommodates theoretically mixed empirical results on the relative labour endowment-skill premium relationship. We further find that the impact on both the relative labour endowment and the skill premium of a rise in investment costs or in the complementarities degree depends on: (i) the absolute productivity advantage of high over low-skilled labour; and (ii) the relative labour endowment.     

Did public wage premiums fuel agglomeration in LDCs?

This paper develops the idea that wage premium jobs cause nearby agglomeration. We show that spatial mobility costs enable wage premiums to cause agglomeration, whereas previous studies crucially assume that wage premium jobs are allocated to favor nearby residents (Harris–Todaro (H–T)). This extends the idea to LDCs, such as Egypt, Ethiopia and Kenya, which have had centralized job allocation mechanisms that do not give a search advantage to locating near public jobs. We show that high public jobs' growth in Egypt has altered regional mobility and population shares in a way that is consistent with agglomeration due to wage premiums and mobility frictions.     

Taxes,female labour supply and household income: differences between the Netherlands and the Federal Republic of Germany

The article investigates the effect of taxes and social premiums on female labour supply and household income. A comparison is made between labour supply and household income between the Netherlands and the Federal Republic of Germany in 1992. A discrete choice model for labour supply is used in which taxes and social premiums are implicitly incorporated. As male labour supply is highly inelastic an individual, male chauvinist model is used. The estimated models are used to simulate the effect of the differences in the tax and social premium system on the differences in labour supply and income between both countries. The results indicate that labour force participation is higher the more individualized the system. The German system leads to a lower tax burden compared to the Dutch system. It is concluded that differences in the tax and social premium system between both countries have hardly any influence on the differences in the inequality of net household labour income. There is evidence that the German system leads to a slightly more unequal distribution of household income. It is also concluded that although the tax and social premium system does influence labour supply and income, it can be doubted whether these effects are substantial.     

A comparison of proxy variable and stochastic latent variable approaches to the measurement of bias in technological change in south african agriculture*

Technical change is inherently unobservable and has conventionally been represented by proxy variables, from simple time trends to more sophisticated knowledge stock variables. This paper follows Lambert and Shonkwiler (1995) in modelling technical change as a stochastic unobservable variable and tests this formulation against the alternative of using R&D and patent indices. This is done by fitting a system of share equations, derived from the dual profit function, to production data for South African agriculture. Each equation includes both unobserved technical change components and technical proxy variables. Variable deletion tests show that conventional proxy variables fail to explain the biases of technological change, while cointegration tests show that technical change is both stochastic and biased. The latent variables provide estimates of biases that are consistent with past studies and the historical record and can be explained by policy change in South Africa following WWII. The demonstration of high rates of return to R&D is not sufficient to justify R&D activity when biased technological change exacerbates input use and welfare distortions within and without the sector. * We thank the University of Pretoria for funding the study and the referees and delegates for many useful comments.
