Risk preferences,production contracts and technology adoption by broiler farmers in China

This study expands on existing research on farmers' risk preferences and technology adoption, with novel analysis of the relationship between risk preferences, production contract participation, and technology investment levels and adoption time. Our analysis uses farm-level data from 345 Chinese broiler growers, and used an instrumental variables strategy and endogenous switching models to address the potential endogeneity of the contracting decision. Both the distance of the farm to the nearest broiler business and the distance of the farm to the nearest market for broiler sale are used as instrumental variables for the contracting decision. Results indicate that farmers with higher risk aversion are more likely to participate in production contracts, less likely to adopt new technology, adopt technology later, and invest less in technology. In the subsample of contract farmers, production contracts with longer terms, lower upfront deposit requirements and higher cost sharing with enterprises for technology adoption may make farmers more likely to adopt technology, to adopt technology early and to invest more. These findings jointly suggest that contract terms that help alleviate credit constraints may be more effective at promoting technology adoption in developing countries.     

Genetic distance and intra-national variation in preferences and behaviours

This paper investigates the relationship between genetic distance and intra-national variation in preferences and behaviours in the Chinese context. We focus on three categories of representative and fundamental preferences—risk, time, and social preferences—and related behaviours. The results suggest that genetic distance is positively related to the differences in risk, time, and social preferences. Furthermore, genetic distance is positively related to the differences in associated economic behaviours, including the differences in entrepreneurship, saving behaviour, cooperative behaviour, and prosocial behaviour. In general, an increase in one standard deviation of genetic distance is associated with an increase in differences in preferences and behaviours by 3–18 % of a standard deviation.     

Constrained Mean-Variance Portfolio Optimization with Alternative Return Estimation

This paper studies the problem of asset allocation in a mean-variance framework. The theoretical model of portfolio optimization is specified and then applied to a long panel data set from historic to most recent times, March 1990 – March 2013. The paper contributes in three ways. First, an alternative asset return model is proposed that combines the historical returns, capital asset pricing model (CAPM) and returns estimated based on firm fundamentals. These return estimates enter the optimization problem. The second contribution is the application of an improved covariance matrix estimator that has superior properties compared to the typical sample covariance estimator. Third, the paper proposes two investments strategies. The first proposition suggests always choosing the maximized Sharpe ratio portfolio and the second one, the portfolio with the highest information ratio. The nature of both strategies is designed for investors with different appetites for risk. The performance of these choices is analyzed in light of four types of constraints: upper/lower investment limits, group constraints and transaction costs. The one-period optimal investment portfolio is rebalanced at quarterly intervals. Both strategies are benchmarked against an alternative investment choice such as holding the S&P 500 index, or investing in a risk-free asset such as a bond. Portfolio analysis and backtesting reveal that the strategies are superior to simply holding an equally weighted portfolio, a risk-free asset or the S&P 500 index.     

An evaluation of the saving,investment, and current account balances of five ASEAN economies

This paper evaluates the saving, investment and current account balances (CABs) of five ASEAN economies: Thailand, Singapore, Indonesia, Malaysia and the Philippines over the period 1976 to 1997. The method is to apply a calibrated representative agent model of optimal saving and investment to each of these economies. The model generates optimal saving, investment and CABs for each year from 1976 to 1997 and these are compared with the actual balances. The results suggest that three of the ASEAN countries—Malaysia, the Philippines and Thailand—had below-optimal current account ratios (to GDP) on average over the period 1976 to 1997, for most reasonable values of parameters. This was the result of over-investment for Malaysia and Thailand and under-saving by the Philippines. For Singapore and, to a lesser extent Indonesia, the reverse applies—their current account ratios were above-optimal on average due to over-saving.     

THE RELATIONSHIP BETWEEN SAVING AND GROWTH IN SOUTH AFRICA: A TIME SERIES ANALYSIS

This paper uses the Johansen VECM estimation technique to examine the directions of association between saving and growth in South Africa over the period 1946–1992. We examine the aggregate private saving rate and its interaction with investment and growth. The paper finds that the private saving rate has a direct, as well as, an indirect effect on growth. The indirect effect is through the private investment rate. In turn, we find that growth has a positive effect on the private saving rate. The extent of this effect is determined by liquidity constraints. Thus, we have a virtuous cycle, as growth enhances saving, which in turn further enhances growth.

International comparison in historical perspective: Reconstructing the 1934-1936 Benchmark purchasing power parity for Japan, Korea, and Taiwan

This article provides the first expenditure-based estimate of purchasing power parity (PPP) converters for 1934-1936 Japan, Korea, and Taiwan. We match all together 70-80 types of goods and services for private consumption, government expenditure and investment using three levels of weights derived from various expenditure surveys. We find that the 1934-1936 average prices of Korea for private consumption, investment, and government expenditure were about 0.86, 0.89, and 0.98 times that of Japan, respectively; and for Taiwan 0.84, 0.87, and 0.95, respectively. This gives the 1934-1936 Korea and Taiwan overall GDE average price levels of 0.87 and 0.86 that of Japan, respectively. Our new benchmark estimate is an improvement over existing converters based either on exchange rates or the 1990 backward projection method, which is embedded with index number biases. It provides a vital link for a long-term overview of structural change, ethnic income distribution, and the historical convergence for these three economies.     

An Index‐Based Model for Determining the Investment Benchmark of Renewable Energy Projects in South Africa

In a globalised world, financial markets observe the optimal level of asset allocation and returns based on risk inherent in the economies. Whether public or private investors, they need to have an optimal return on their investment given the finite resources. In relatively new sectors like grid‐connected renewable energy, many investors face difficulty in assessing proper return, making them more averse to financing such projects, affecting transborder project development opportunities. In developing countries like South Africa, which has tremendous potential for renewable energy projects, an arbitrary choice of the required rate of return for project evaluations can negatively affect funding decisions. This paper explores an index‐based model to make fair estimates of the required equity benchmark internal rate of return (IRR) using financial markets observation for renewable energy projects in South Africa. The index‐based model is parsimonious and captures common macroeconomic factors. More specifically, it provides a simple and effective mechanism to calculate IRR for renewable energy projects given different gestation periods.     

Investment incentives and the relative demand for skilled labor: Evidence from accelerated depreciation policies in China

This study evaluates the effects of China's 2014 and 2015 accelerated depreciation policies on the relative demand of firms for skilled labor. We develop a simple model to explore how the policies affect the relative demand of firms for skilled labor and illustrate the roles of financing constraints and tax compliance in mediating the policy effects. We then employ a firm-level dataset from China's A-share listed companies and use a quasi-experimental design to examine the model predictions. We find that the policies significantly increase the relative demand of firms for skilled labor. The channels underlying the policy effects are that the policies generate additional cash flow for firms, stimulate investment and, thus, raise the demand of firms for skilled labor with the presence of capital–skill complementarity. We also find that the positive effects of the policies on the relative demand for skilled labor are primarily significant for firms with strong financing constraints and high tax compliance. Moreover, we document the positive effects of the policies on R&D investment, firm value added, productivity, workers' benefits, and corporate social responsibility performance, which further corroborate our main results.     

Knowing when to splurge: Precautionary saving and Chinese-Canadians

Why do household saving rates differ so much across countries? This micro-level question has global implications: countries that systematically “over-save” export capital by running current account surpluses. In recipient countries, interest rates are therefore too low and financial stability is put at risk. Existing theories argue that saving is precautionary; however tests of these theories are limited to cross-country comparisons and the results are mixed. We report the findings of an original survey experiment. Using a simulated financial saving task implemented online, we compare the saving preferences of a large and diverse sample of Chinese-Canadians with other Canadians. This comparison is instructive given that Chinese-Canadians migrated from, or descend from those who migrated from, a high-saving environment to a low-saving, high-debt environment. We also compare behavior in the presence and absence of a simulated “welfare state”, which we represent in the form of mandatory insurance. Our respondents exhibit behavior in the saving task that corresponds to standard economic assumptions about lifecycle savings and risk-aversion. We find strong evidence that precautionary saving is reduced when a mandatory insurance is present, but no sign that Chinese cultural influences, represented in either linguistic or ethnic terms, have any effect on saving behavior. Overall, the results suggest that Chinese “over-saving” is likely to be addressed when more generous welfare state policies are put in place.     

Financial crisis and saving–investment dynamics in the presence of cross-sectional dependence: The case of East Asia

Using the common correlated effects mean group (CCEMG) technique to a set of balanced panel error correction model, we examine the effects of the Asian financial crisis of 1997, and the global financial crisis of 2008 on the behavior of saving and investment in East Asian countries. Our results show that saving and investment rates are highly dependent across countries of East Asia. This finding underlines the importance of taking into account cross-sectional dependence when analyzing saving–investment relationship. The results also indicate that the adverse financial shock of 1997 has negatively affected the short run correlation between saving and investment, but has not influenced their long run relationship. Our finding, hence, verifies the prediction of new open economy macroeconomic theories regarding the divergence of short run saving–investment from its long run trend for East Asia. Moreover, we find that the global financial crisis of 2008 has not affected the saving–investment dynamics in this region. It means that the consequences of the Asian and global financial crises for saving–investment dynamics are not the same in East Asia. One might attribute these differences to the origins of these two shocks, i.e., internal versus external to the region. These findings may have some policy implications for those countries that rely heavily on foreign investment and are subject to various internal and external financial shocks.     

The relationship between saving and investment for Japan

In this paper, we revisit the saving and investment nexus as postulated by Feldstein and Horioka (FH) [Econ. J. 90 (1980) 314]. We test for cointegration between saving and investment using the recently developed bounds testing approach to cointegration and derive the long-run elasticities using the autoregressive distributed lag modeling approach for Japan over the period 1960–1999. We establish the unit root properties of the data in the presence of structural break(s) using the Zivot and Andrews (ZA) [J. Business Econ. Stat. 10 (1992) 251] and the Lumsdaine and Papell (LP) [Rev. Econ. Stat. 79 (1997) 212] tests. Finally, we ascertain the direction of causation between saving and investment by using the bootstrap approach. Amongst our key results we find that saving and investment are cointegrated for Japan; investment causes saving and saving causes investment; shocks to saving and investment have a permanent effect; and the long-run coefficient on saving is 0.68, implying a moderate rate of correlation. From the latter finding, we believe that there is no puzzle between saving and investment in the case of Japan, a result contrary to FH (1980).     

Competitive blind spots and the cyclicality of investment: Experimental evidence

We report laboratory experiments investigating the cyclicality of profit-enhancing investment in a competitive environment. In our setting, optimal investment is counter-cyclical when investment costs fall following market downturns. However, we do not observe counter-cyclical investment. Instead, we see much less strategic behavior than our rational investment model anticipates. Our participants exhibit what Porter (1980) terms a competitive blind spot, and heuristic investment models where individuals invest a fixed percentage of their liquidity, or a fixed percentage of anticipated market demand, better fit our data than does optimal investment. We also report a control treatment without cost changes and a treatment with asymmetric investment liquidity. Both of these extensions support our main result.

Household savings in China

The domestic saving rate in China is the highest in the world and it surpasses the investment share in GDP, which is also very high by international standards. This excessive saving results in a large current account surplus. Understanding why the Chinese save so much is a central issue in the debate on global imbalances. The goal of our paper is to analyse empirically Chinese household saving behaviour taking into account the disparities within the country, at the provincial level and between rural and urban households. We first show that, notwithstanding the rising contribution of government and firms to national savings the real peculiarity lies with Chinese families. We move from Modigliani and Cao's (2004) attempt to explain rising personal saving in China within the life cycle hypothesis and show how a more careful analysis indicates that life-cycle determinants do not suffice, especially in the most recent period. Once we consider regional differences and distinguish urban and rural households using provincial-level data, it becomes clear that additional explanations are needed and that precautionary motives and liquidity constraints are playing an important role. Our results suggest that in order to reduce the propensity to save of Chinese households it is necessary to improve social services provision and to facilitate the access to credit.

Financing and monitoring in an emerging economy: Can investment efficiency be increased?

This study investigates the influence of the financial system on firms' investment efficiency in China. For this purpose, we employ country level data of capital markets and financial institutions along with financial data from 2797 Chinese firms in the period from 1998 to 2015. The firms are priori classified into four groups, by high and low values of financial constraints and agency problems. Results show that financial development influences firms' investments positively either directly or by reducing cash flow sensitivity. The impact remains the same for all types of firms. Moreover, the financial structure has an impact on investment efficiency of firms; this result also remains the same even after controlling levels of financial development. Study contributes that capital market based financial structure impacts investment decisions by reducing financing constraints and agency issue due to its strong monitoring ability.     

Selecting public goods institutions: Who likes to punish and reward?

We study the link between individual attitudes toward uncertainty on the one hand, and preferences over, as well as behavior within, various public goods institutions on the other hand. We incentive‐compatibly elicit preferences over voluntary contribution mechanisms with and without reward and punishment options and then randomly assign subjects to play in one of the four institutions. We find that payoffs are significantly greater when punishment is allowed but that only a small minority of participants prefers such an environment. Somewhat surprisingly, preferences over institutions are generally independent of individual characteristics. Conversely, individual characteristics, including institutional preferences, are significantly predictive of behavior in the public goods game. For instance, risk‐averse individuals preemptively punish more often. This suggests that when studying sanctions and rewards, it is important to consider individual attitudes toward risk and uncertainty—although they may not affect the original selection into institutions.

How to Share Our Risks Efficiently? Principles for Optimal Social Insurance and Pension Provision

The efficient organisation of social insurance is an important problem for modern societies. The paper discusses evidence that shocks in labour income have largely persistent effects and analyses the implications of this observation for the optimal design of institutions for wage contracting, social security, and pensions. In an optimal contract, wages reflect variations in individual productivity for incentives reasons. However, the optimal contract insures workers against firm specific shocks. These can better be born by shareholders who can diversify risks on capital markets. Progressive income taxation provides further insurance. On top of that there is scope for additional insurance based on ‘verifiable’ information on unemployment and health conditions. As final form of ‘insurance’, the paper analyzes the role of self-insurance. Income shocks can be absorbed partially by precautionary saving. The individual’s saving plans for retirement and for precaution are, therefore, related issues. In an institutional setting with mandatory saving for retirement, an integration of disability and unemployment insurance on the one hand and the pension system on the other hand in a lifetime savings account allows for this interrelation. The paper analyzes how to deal with the uncertainty in the return on savings in the framework of a lifetime saving account.
