Is it an offence to overcharge?

This paper considers whether a trader commits an offence when he makes a mistake and overcharges a customer. It examines the offences found in section 20 of the Consumer Protection Act 1987 - as defined in section 21(1)(a) - and looks at the effect of a recent decision of the appeal courts.     

CONSEQUENCES OF MINIMUM WAGE INDEXING

During the 1980s, the minimum wage fell relative to prices and average wages in the U.S. economy. If the minimum to average wage ratio had been constant at the level maintained through the 1970s, the minimum wage would have been $5.51 in 1993. If the 1993 minimum wage had increased to $5.51, payments to minimum wage workers would have increased by an estimated $20.3 billion, and the number of people earning that wage would have risen from 2.0 million to 14.7 million. Elasticity estimates generated from other studies indicate that employment would have fallen 240,000 (4.4%) among 16–19 year olds and 349,000 (3.0%) among 20–24 year olds. Wage payments to minimum wage workers would have substantially increased, but the effect on family income distribution would have been small. Many minimum wage workers are children living with parents or adults in a family with other earners. Consequently, 75% of minimum wage workers account for less than half of their family's income.     

A Note: Natural Generalization of Black-Scholes in the Presence of Skewness,Using Stable Processes

The Lognormal price model is generalized to the class of Log-Stable Processes, a family which possesses self-similarity properties usually only associated with the Lognormal, but which, more generally, can model negatively skewed distributions of return. This generalization appears to explain several discrepancies between the Black-Scholes Model and observed market phenomena, such as the variation of implied volatility of option price with exercise price and term to expiry, and the nonzero probability of bankruptcy or ‘crash’. It will be argued that the class of maximally negatively skewed Stable distributions (a class which, paradoxically, contains the normal) may be utilized to produce models which imply these phenomena naturally.     

Cream-Skimming or Profit-Sharing? The Curious Role of Purchased Order Flow

Purchased order flow refers to the practice of dealers or trading locales paying brokers for retail order flow. It is alleged that such agreements are used to “cream skim” uninformed liquidity trades, leaving the information-based trades to established markets. We develop a test of this hypothesis, using a model of the stochastic process of trades. We then estimate the model for a sample of stocks known to be used in order purchase agreements that trade on the New York Stock Exchange (NYSE) and the Cincinnati Stock Exchange. Our main empirical result is that there is a significant difference in the information content of orders executed in New York and Cincinnati, and that this difference is consistant with cream-skimming.     

Forward Discount Bias: Is it Near-Rationality in the Foreign Exchange Market?*

A risk-averse US investor adjusts the shares of a portfolio of short-term nominal domestic and foreign assets to maximize expected utility. The optimal strategy is to respond immediately to all new information which arrives weekly. We develop a model to estimate the cost of optimizing less frequently and find that it is generally very small. For example, if the investor adjusts portfolio shares every three months, an average expected utility loss of 0.16 per cent p.a. is incurred. Hence, slight opportunity costs of frequent optimization may outweigh the benefits. This result may help explain forward discount bias.     

The Long-Run Negative Drift of Post-Listing Stock Returns

After firms move trading in their stock to the American or New York Stock Exchanges, stock returns are generally poor. Although many listing firms issue equity around the time of listing, post-listing performance is not entirely explained by the equity issuance puzzle. Similar to the conclusions regarding other long-run phenomena, poor post-listing performance appears related to managers timing their application for listing. Managers of smaller firms, where initial listing requirements may be more binding, tend to apply for listing before a decline in performance. Poor post-listing performance is not observed in larger firms.     

Monastic mortality: Durham Priory, 1395–15291

This article presents reliable data on the life expectancy of the monks of Durham Priory between 1395 and 1529. The number of years that monks survived in this northern monastery plunged precipitously in the second half of the fifteenth century before staging a partial recovery in the early sixteenth. The experience of Durham monks mirrors the scale, direction, and timing of the data already produced for the monks of Canterbury and Westminster. While the precise relationship between monastic mortality and that of the population at large remains difficult to determine, there can be no doubt that the symmetry that has been established between mortality in three monasteries located in different parts of the country has important implications for our understanding of the demographic history of late medieval England.     

STOP US BEFORE WE SPEND AGAIN: INSTITUTIONAL CONSTRAINTS ON GOVERNMENT SPENDING

A distributive politics model establishes that the presence of exogenously enforceable spending limits reduces spending and that the effect of executive veto authority is contingent on whether spending is capped and whether the chief executive is a liberal or conservative. Surprisingly, when spending limits are in place, governments with conservative executives spend more than those with more liberal chief executives. Limits are welfare improving, as is the executive veto when it leads to the building of override coalitions. Using 32 years of US state budget data, this paper also establishes empirically that strict balanced budget rules constrain spending and also lead to less pronounced short-term responses to fluctuations in a state's economy. Party variables like divided government and party control of state legislatures tend to have little or no direct effect, with political institutions and economic indicators explaining much of the variation in state spending.
