The impact of union-sponsored boycotts on the stock prices of target firms

An empirical analysis of the impact of union-sponsored boycotts on the stock prices of target firms strongly suggests that union boycott announcements initially lead to economically and statistically significant losses in the stock prices of the target firms. However, this short-term price decline is almost completely erased by rebounds in stock prices over the ensuing 15 trading days.     

QUANTITATIVE EASING AND THE UK STOCK MARKET: DOES THE BANK OF ENGLAND INFORMATION DISSEMINATION STRATEGY MATTER?

We use intraday aggregate stock market data and an event‐study framework to assess the UK's equity market reaction to the unexpected element of the Bank of England Monetary Policy Committee's (MPC) asset purchase announcements for the 2009–2017 period. We assess the reactions of equity returns and their volatility over various time frames, both preceding and following the MPC announcements. Our results show that the UK unconventional monetary policy shocks have a significant impact on domestic equity returns and volatilities. The strength of this impact depends on the Bank's information dissemination through inflation reports and the publication of the MPC's voting records. (JEL G14, E44, E52)     

How unions affect shareholder wealth in firms announcing layoffs

We investigate whether investor anticipation of future performance differs between union and nonunion firms following corporate layoff announcements. Using event-study methodology and multivariate regression analysis, we find that the stock market reaction to layoff announcements is negatively related to nonunion firms and positively related to union firms.     

The Texaco racial discrimination case and shareholder wealth

We analyze the wealth ejfects of the Texaco racial discrimination lawsuit both on the shareholders of Texaco and its major U.S. competitors. Employing a comprehensive data set which included every case docket entry and every Wall Street Journal article on the case as an experimental stimulus, our findings suggest that the overall cost of the case to Texaco shareholders exceeded $500 million, that Texaco's tribulations had little, if any, impact on the share prices of its major competitors, and that Wall Street Journal coverage of the case was highly correlated with significant changes in Texaco stock prices. This last finding provides significant support for Hite 's suppostion that newspaper editors “key ” on ex post stock price changes in selecting the events to be covered in the next day's edition.

RBI’s Monetary Policy and Macroeconomic Announcements: Impact on S&P CNX Nifty VIX

This study investigates the information content of RBI’s monetary policy and macroeconomic announcements and its impact on the implied volatility index. The empirical findings suggest that implied volatility (VIX) increases prior to the scheduled macroeconomic announcements. This study takes into account the RBI’s (Reserve Bank of India) monetary policy in the form of monetary credit information review meeting days, consumer price index, wholesale/producers price index, index of industrial production, employment report, gross domestic product. The empirical result explains that investors regard the scheduled macroeconomic announcements in the valuation of their financial assets. More specifically study shows that investors jointly consider the MCIR and GDP reports for their financial planning. This study contributes in two ways; it is useful in the forecasting of short-term market volatility and pricing of Options.     

QUALITY DIFFERENCES,THIRD‐DEGREE PRICE DISCRIMINATION,AND WELFARE

We propose a model with two markets to analyze the welfare implications of price discrimination with quality differences. In each market a local firm that operates in that market only competes against a global firm that operates in both markets. Local firms produce higher‐quality goods than the global firm. If the quality levels of the local firms' products are the same, price discrimination is never welfare‐decreasing. If they differ, discrimination is welfare‐increasing if quantity increases. Because of a positive allocation effect of price discrimination, there are parameter values such that welfare increases while total output decreases with price discrimination. (JEL D43, D60)     

DISCOUNT PRICING

We investigate the practice of framing a price as a discount from an earlier price, with information such as “was $200, now $100.” We discuss two reasons why a discounted price—rather than a merely low price—can make a consumer more willing to purchase. First, a high initial price can indicate the seller has chosen to supply a high-quality product. Second, when a seller with limited stock runs a clearance sale, later consumers infer that unsold stock has higher expected quality when its initial price was higher. We also suggest a behavioral explanation, which is that consumers with reference-dependence preferences are more likely to buy if they perceive the price as a bargain relative to the earlier price. Discount pricing is therefore an effective marketing technique, and a seller may wish to deceive potential customers by offering a false discount. The welfare effects of regulation to prevent fictitious pricing are subtle, with potential unintended consequences, and depend on whether consumers are sophisticated or naive. (JEL D18, D42, D83, L15, M31)     

THE WELFARE EFFECTS OF THIRD‐DEGREE PRICE DISCRIMINATION IN A DIFFERENTIATED OLIGOPOLY

This article examines the welfare effects of third‐degree price discrimination under oligopolistic competition with horizontal product differentiation. We derive a necessary and sufficient condition for price discrimination to improve social welfare: the degree of substitution must be sufficiently greater in the “strong” market (where the discriminatory price is higher than the uniform price) than in the “weak” market (where it is lower). It is verified, however, that consumer surplus is never improved; social welfare improves solely owing to an increase in the firms' profits in the case of linear demands. (JEL D43, L11, L13)     

PRICE DISCRIMINATION IN RELATED MARKETS

The Pigou-Robinson pricing rule for third degree monopolistic price discrimination states that price ratios vary inversely with ratios of direct price elasticities of demand. The rule holds when markets are sealed, and cross price elasticities of demand are zero. We show how the rule can fail when imperfect sealing permits leakage. We also develop a general discriminatory pricing rule that holds when leakage causes market demands to be related. The general pricing rule is based on all direct price elasticities of demand, all cross price elasticities of demand, and the size distribution of the markets     

Stale economic news,media and the stock market

I employ a classification of headlines from newspapers and wire services to examine whether stale macroeconomic news affects stock prices. Unlike with individual stocks, the cost of obtaining information about major economic releases is relatively low. Thus, stock prices should adjust to economic news announcements prior to their coverage in newspapers. I find statistically and economically significant relationship between stale news stories on unemployment and next week’s S&P 500 returns. This effect is then completely reversed during the following week. These findings show that investors are affected by salient information and support the hypothesis that investors overreact to stale macroeconomic news reported in newspapers.     

IS THERE ADVERSE SELECTION IN LIFE INSURANCE MARKETS?

Adverse selection theory predicts people with a high risk of death are more likely to own life insurance. Using a unique data set merging administrative and survey records, we test this theory and find the opposite: people with high death risk are less likely to own life insurance. We postulate advantageous selection and price discrimination swamp adverse selection in individual life insurance markets. To determine which effect is more powerful, we analyze group life insurance markets, where insurance companies cannot price discriminate as well as in individual markets. Our data suggest that price discrimination has a stronger effect than advantageous selection. (JEL D8, G1, I1)     

RETAIL REDLINING: ARE GASOLINE PRICES HIGHER IN POOR AND MINORITY NEIGHBORHOODS?

This study uses new data on retail gasoline prices in three cities to provide evidence on the relationship between neighborhood characteristics and consumer prices. We find that prices do not vary greatly with neighborhood racial composition, but that prices are higher in poor neighborhoods. For a 10% point increase in poor families relative to middle‐upper income families, retail gasoline prices increase by an average of 0.70%. Two‐thirds of this differential is explained by cost, competition, and demand characteristics of poor neighborhoods. The remaining differential likely reflects price discrimination in response to lower competition and/or more inelastic demand in poor neighborhoods. (JEL D43, J15, L71)     

Monetary Policy Announcements and Stock Returns: Evidence from the Pakistani Market

Objective of this paper is to analyze the impact of monetary policy announcements on stock returns. Event window of 31 days and an estimation window of 250 days was constructed. ARIMA model is applied to calculate the estimated returns from estimation window (t ? 250). Abnormal returns were calculated by taking the difference between actual and estimated returns. Then abnormal returns were aggregated as cumulative abnormal returns (CAR). CAR at 30% showed an impact of monetary policy announcements on stock returns. Null hypothesis of zero abnormal returns was rejected since the results were found in critical region under normal distribution. Further, we decomposed the interest rate into expected and un-expected to analyze their impact on stock returns. After checking for stationarity, Engle–Granger co-integration test were applied to check long run relationship between interest rates and stock return. A significant effect of interest rates (expected and un-expected) was observed in the short run. These results are in line with Kuttner’s (J Monet Econ 47:523–544, 2001), Bernanke and Kuttner’s (J Financ 60:1221–1257, 2005), Bredin et al.’s (US stock returns the impact of domestic monetary policy shocks, http://www.ucd.ie/t4cms/wp0604.pdf, 2007) and Ehrmann and Fratzscher’s (Equal size, equal role? Interest rate interdependence between the Euro Area and the United States, European Central Bank Working Paper 342, 2004). The study finds evidence of LR relationship between un-expected interest rates and whereas expected interest rates and stock returns have short term relationship.     

The Labor Market Effects of Sex and Race Discrimination Laws

We study the effects of state sex and race discrimination laws that were passed prior to federal antidiscrimination legislation. State sex discrimination laws targeted discrimination in pay only. Because an equal pay constraint raises the relative price of female labor, we would expect the relative employment of females to decline. We find robust evidence that state equal pay laws for women reduced relative employment of both black women and white women. We also find some evidence of positive effects of race discrimination laws on earnings of blacks relative to whites, although no evidence of employment effects. (JEL J15 , J16 , J18 , J23 )     

Roles of Stock Price and Exchange Rate in Slovakia's Money Demand Function and Policy Implications

The demand for real M1 in Slovakia is positively influenced by real output and the stock price and negatively associated with the deposit rate, depreciation of the koruna, the euro interest rate, and the expected inflation rate. Considering the goods and the money market simultaneously, these results suggest that a higher stock price may or may not cause real output to rise and that a depreciation of the koruna or a higher euro interest rate would help raise Slovakia's real output. The coefficients of the deposit rate and the stock price in real M2 demand are insignificant at the 10% level. The likelihood ratio test in the extended Box–Cox model shows that the double-log form cannot be rejected at the 5% level while the linear form can be rejected at the 5% level. The CUSUM and CUSUMSQ tests show that the money demand function was relatively stable.      

HOW TO HAGGLE and TO STAY FIRM: BARTER AS HIDDEN PRICE DISCRIMINATION

Barter transactions, conducted openly by established corporations, play an increasingly significant role in the U.S. economy. The model developed here helps explain why firms use barter and yields predictions concerning the circumstances under which barter is likely to occur. It is shown that when two firms barter goods used as inputs, price discrimination occurs. This price discrimination is hidden from the firms' other customers because the real values of the transacted goods to the barterers are different from the accounting prices used in the transaction. Since price discrimination that is observed by potential customers might have an adverse effect on the selling firm's future bargaining power, barter will have value as a means of hiding price discrimination.     

MANAGERS' COMPENSATION AND MISREPORTING: A COSTLY STATE VERIFICATION APPROACH

We look for the optimal shareholder-manager contract leading to high effort and truthful revelation of firm performance. This twofold incentive compatibility constraint calls for a convex compensation scheme (a fixed wage plus a stock option) coupled with a state contingent audit. In order to reduce expected verification costs, an optimal stock option plan assigns the manager a large number of options with high strike price. It is suggested that focusing the audit activity (and supervision) on the exercise of stock option packages is a better solution to the problem of misreporting than giving up stock options as a compensation tool.

FORECASTING CRUDE OIL PRICE MOVEMENTS WITH OIL‐SENSITIVE STOCKS

This paper uses monthly data from 1984:M10 to 2012:M8 to show that oil‐sensitive stock price indices, particularly those in the energy sector, have strong power in predicting nominal and real crude oil prices at short horizons (1‐month‐ahead predictions), using both in‐ and out‐of‐sample tests. In particular, the forecasts based on oil‐sensitive stock price indices are able to outperform significantly the no‐change forecasts. For example, using the NYSE Arca (AMEX) oil index as a predictor, the 1‐month‐ahead forecasts for nominal crude oil prices reduce the mean squared prediction error by between 22% (for the West Texas Intermediate oil price) and 28% (for the Dubai oil price). Moreover, we find that the directional forecast based on the AMEX oil index is significantly better than a 50:50 coin toss. The novelty of this analysis is that it proposes a new and valuable predictor that both reflects timely market information and is readily available for forecasting the spot oil price.(JEL G17, Q43, Q47, C53)     

Price Discrimination with Differentiated Products: Definition and Identification

There is no widely accepted definition of price discrimination with differentiated products. Either absolute price-cost differences or percentage price-cost markups are used as benchmarks for comparison. I show that the two criteria are qualitatively different: One may indicate price discrimination when the other does not. Moreover, anything other than marginal cost pricing will be identified as price discrimination by at least one of the two. I propose choosing a criterion based on the cost of arbitrage in the market under examination. Because this is often difficult to determine, it is advisable to always report results with both measures.     

A GUIDE TO THE PITFALLS OF IDENTIFYING PRICE DISCRIMINATION

This paper demonstrates that plausible cost-based explanations exist for what are commonly perceived to be cases of price discrimination. We explain such commonly discussed problems as the price spreads of retail gasoline products, the "high" price of dinners at restaurants, the "high" price of popcorn at movie theaters, and the fact that airline ticket prices vary with how long the ticket is purchased before the flight's departure. Our explanations benefit from not relying on consumer ignorance or implicit collusion among numerous sellers.
