Order Flows,Investor Sentiments and Feedback Trade in Index Futures Market

This paper examines the presence of feedback trading, and investor sentiment drove feedback trading by traders in the Nifty 50 index futures contract in India. The results of the study using high-frequency data sampled at 10 min interval using VAR and contemporaneous VAR model as applied to market microstructure settings reveals negative evidence of feedback trade and investor sentiment-driven feedback trade in Nifty 50 futures contract. Further, consistency with noise trading hypothesis, order flows in Nifty 50 futures contract is less informative when traders are overly optimistic.

     

On tariff and quality innovation in a market with discrete preferences

In a market for a quality-differentiated good with heterogeneous set of consumers and a local firm facing competitive imports from abroad, we examine private and social incentives for quality innovation. For differential tariff regime, we show that both the private and social gains increase with the tariff protection for the low-quality segment of the domestic market for any given tariff on high-quality imports. But for some very high costs of innovation, the local firm may not undertake a socially desirable innovation. The pro-competitive effect, on the other hand, ensures that quality-distortion-at-the-bottom occurs only for very high levels of tariffs.     

Managerial incentives and corporate control auctions

An analysis of the sequence of bidding in corporate control contests involving white knights reveals a category of white knights termed as ‘delayed bid’ white knights who make their bid after two consecutive hostile bids. The ‘immediate bid’ white knights make their bid in relative haste after the first hostile bid. Overpayments by white knights are much larger for the ‘immediate bid’ white knights. An analysis of the respective compensation packages shows that the managers of the ‘immediate bid’ white knights have a lower proportion of their income linked to stock value (relative to their annual cash income) compared to ‘delayed bid’ white knights and hostile bidders.     

A study of biotechnology start-ups undergoing leadership change: Antecedents of change and endogenous performance consequences

One of the most important decisions that a new biotechnology firm faces is whether to replace its founding CEO, who often has been involved with the invention of the firm's core technology, with a more professional manager, who has broader commercialization skills to help the firm to grow into a viable business. In this paper, we argue that leadership change away from the founding CEO is influenced strongly by the interests of key stakeholders and that the endogeneity inherent in the change (or non-change) influences firm performance. As the context surrounding decision-making changes from pre-patent to post-IPO, key stakeholders often may not view what is best for the firm and best for self-interest in the same way. Using data on change in leadership at 135 U.S. biotechnology equipment firms, we find evidence that the context in which decisions are being made influences which of the various competing interests will take precedence. The results further confirm the importance of controlling for endogeneity in decision-making when examining firm performance.     

Regulation,reputation, and environmental risk

This paper examines how preferences for social reputation affect the design of monetary incentives in an efficient mechanism for environmental risk. Our results are a high reputation firm receives less than optimal transfer; the low reputation firm sacrifices information rent.     

Does trade size restriction affect trading behavior? Evidence from Indian single stock futures market

Algorithmic traders use their advantage of speed to execute a large number of small-sized trades in a very short time. In the presence of a minimum trading unit (MTU) restriction, they are forced to trade at the smallest possible sizes, often restricted by the MTU. Using a novel data set of single stock futures market obtained from the National Stock Exchange of India, we show that the MTU restriction acts as a binding constraint for traders while optimizing trade sizes. Contrary to expectation, we find weak evidence that liquidity is positively impacted by the contract size revision.     

Friend or Foe? The effects of contingent employees on standard employees' work attitudes

Using data from a large-scale national survey of employers and employees in Britain, we examine the impact of the presence of contingent employees on work attitudes of standard (full-time, indefinite-term) employees. Drawing on differing explanations for the increased use of contingent employment arrangements, we derive competing hypotheses about how this use affects standard employees' work perceptions and attitudes, and explore the impact of a number of potentially intervening factors. We find that contingent employees have little effect on standard employees' perceptions of work overload, but strongly reduce perceived job security, which in turn, mediates the negative effects of contingent employees on job satisfaction and organizational loyalty.     

Testing for PPP: Should we use panel methods?

A common finding in the empirical literature on the validity of purchasing power parity (PPP) is that it holds when tested for in panel data, but not in univariate (i.e. country-specific) analysis. The usual explanation for this mismatch is that panel tests for unit roots are more powerful than their univariate counterparts. In this paper we suggest an alternative explanation. Existing panel methods assume that cross-unit cointegrating relationships, that would tie the units of the panel together, are not present. Using simulations, we show that if this important underlying assumption of panel unit root tests is violated, the empirical size of the tests is substantially higher than the nominal level, and the null hypothesis of a unit root is rejected too often even when it is true. More generally, this finding warns against the automatic use of panel methods for testing for unit roots in macroeconomic time series.First version received: November 2001/Final version received : October 2003
