Herding in Chinese stock markets: a nonparametric approach

The paper reports new evidence of herding in the Chinese A-type and B-type markets by employing nonparametric kernel regression. We find statistically significant evidence of herding in A-type market under both extreme high and low market returns. Herding in B-type market, which predominantly consists of foreign investors, indicates only weak evidence of herding. We do not find any statistically significant evidence of herding in the pre-2001 sample of B-type market, when only foreign investors could do the trading. Lack of knowledge and experience of local investors may be attributed to the presence of herd behaviour in the Chinese markets.     

Revisiting the democracy-private investment nexus: Does inequality matter?

Contrary to the predictions of a large theoretical literature, recent cross-country evidence suggests autocracies can generate statistically indistinguishable levels of private investment compared to democracies. We argue that the previous exclusion of inequality explains part of this puzzle. We model current investment as a function of investors’ beliefs about future tax rates, which are conditioned by the constraints on the Executive in setting tax rates and expropriating tax revenues. In democracies, where tax rates reflect the preferences of the median voter, investment declines with rising inequality. In autocracies, investor beliefs about future tax rates reflect the relative power of Elites compared to the Executive. As inequality rises, the increased resources available to Elites constrains the Executive’s ability to expropriate more tax revenues. The heterogeneous determinants of investor beliefs can explain the observed pattern of investment across regime types. We first test our predictions at the macro-level with cross-country data. We then test the behavioral underpinnings of our model with a novel laboratory experiment showing how inequality affects individual-level investment behavior dependent upon regime type. Results from both types of analyses show that when inequality is taken into account autocracies can generate similar levels of investment to democracies.     

Budget over health unless overweight: A Solomon four‐group study

Budget and health motivations for food purchase (e.g., discounts and health consciousness, respectively) affect consumer choice while shopping and well‐being afterward. However, not all findings from research have suggested that discounts/taxations on healthy/unhealthy food encourage health‐conscious food choice. On the other hand, the consumer behaviour line of research on the influence of front‐of‐package health messages has mostly echoed similar results that such communication leads to overconsumption; thus, obesity. We examined the influence of market practices targeting consumers’ budget and health‐related motivations for food purchase in a 2 (price: recommended retail price, discount price) × 2 (product: regular potato chips, potato chips with ‘75% less saturated fat’) experiment using six Solomon four‐group designs. Our results indicate that overweight consumers are not prone to discounts, unlike their normal‐weight counterparts. A price cut nullifies the influence of health messages on purchase intentions among normal‐weight buyers when the regular and healthier packaged foods are both on discount.     

Optimal privatization of vertical public utilities

Abstract We examine restructuring, divestiture, and deregulation of a vertically integrated public utility, (e.g., electricity), from a public finance perspective. How an optimal restructuring plan for the utility depends on the cost of public funds and on the X‐efficiency gains from privatization, how the optimal degree of competition in the upstream and downstream segments are connected, and implications of privatization for consumer prices are examined. The higher the cost of public funds, the more likely the post‐privatization price will exceed the regulated public utility price. The greater the X‐efficiency gains from privatization, the more likely the post‐privatization price will fall.     

With whom do you trade? Defensive innovation and the skill‐bias

Abstract We examine whether increased trade with countries with ineffective protection of intellectual property has contributed to the skill‐deepening of the 1980s. We construct an index of effective protection of intellectual property at the country level, combining data on protection of patents and rule of law. Next, we construct an industry‐specific version of this index, using as weights each country's trade share in the total trade of the industry. We find a decline in this trade‐weighted index, owing to a rise in trade with countries with low effective protection of intellectual property, which explains 29% of the rise in within‐industry skill‐intensity.     

Distributive Politics and Electoral Competition

Within the framework of pure redistribution (dividing one unit of a homo- geneous good among identical individuals), the paper analyses the redistribution that arises from Downsian, two-party, electoral competition. It appears that the strategic behavior of vote-maximizing parties leads them to propose divisions which are not far from the egalitarian one.

Stock markets in transition: the Warsaw experiment1

This paper investigates the development from 1991 to 1994 of the Warsaw Stock Exchange, which opened on April 16th, 1991. An overview is presented focusing first on the deepening of the equity market, with a still limited but increasing number of listed companies, and then on the high trading activity and price dynamics with their impressive outburst in 1993. Three important dimensions are thereafter analyzed: the relevance of organizational and regulatory choices, the degree of market inefficiency and the origin of the discrepancy between IPO prices and first quoted market prices. Concluding remarks concentrate on the market's ability to fulfil its fundamental tasks.     

Heterogeneous Expectations,Short Sales Regulation,and the Risk-Return Relationship

This paper examines, in a Canadian context, the effect of short sales regulation on the risk-return relationship. It shows that, theoretically, the opportunity cost induced by short sales regulation is positively related to the dispersion of agents' beliefs and negatively related to the security's liquidity level. The model is tested over the sixty-month period from January 1985 through December 1989. All the 13,079 observations are pooled into a time series cross-sectional model. The results corroborate that a negative linear relationship links expected risky asset returns and the divergence of agents' beliefs. This negative relationship is consistent with the presence of opportunity costs resulting from short sales regulation when return beliefs are heterogeneous. However, the negative relationship between security returns and dispersion of beliefs is essentially confined to illiquid securities, that is, those monitored by a small number of analysts.     

A particular class of continuous-time stochastic growth models

This paper generalizes to uncertaintly the neoclassical one-sector model by transforming the basic differential equation on the capital labor ratio into a “stochastic” differential equation. The capital-labor ratio and related economic variables become random variables whose probability distributions vary with time, and the paper is focused on the existence of a steady state denfined by the (probabilistic) stationarity of these variables. An application of the results is given for a specific example with a Cobb-Douglas production function and uncertainty on the saving coefficient, the labor-force rate of growth, and the capital depreciation rate.
