This article argues by casual empirics that a low draw percent in chess may work as a simplified cheating indicator. Data from a large number of historical chess games (53331) indicate that this extremely simple heuristic may be used as a first test if suspicion of cheating arises for professional chess players. This heuristic does not prove any cheating, but it may be applied as a quick primal indicator of potential cheating behaviour for a player suspected of cheating.

We analyze optimal sentence length for recurring crimes in the face of adjudication errors. We develop an infinite-horizon model where offenders are habitual — they repeat crimes whenever free. If apprehended, criminals may be wrongfully acquitted. Similarly, innocent people may be apprehended and wrongfully convicted. The key result shows how the risks of wrongful convictions and wrongful acquittals affect optimal sentencing. For reasonable ranges of parameter values, the two types of adjudication errors have the same qualitative effect on optimal sentencing: a greater risk of any of the two adjudication errors leads to a decrease in optimal sentencing.

We investigate a model of a series of contests in which a contestant's past and present success gives a head start over a rival in the future. How this advantage from winning affects contestants' efforts, whether the laggard gives up or keeps on fighting, and how the head start develops over time, are key issues. We find that the expected effort of the laggard will always be higher than the rival at some stage in the series of contests, and this is most likely to happen when at a large disadvantage or at a late stage in the series.

In many two-sidedmarkets we observe that there is a common distributor on one side of the market. One example is the TV industry,where TV channels choose advertising prices to maximize own profit and typically delegate determination of viewer prices to independent distributors.We showthat in such amarket structure the stronger the competition between the TV channels, the greater will joint profits in the TV industry be. We also show that joint profits may be higher if the wholesale contract between each TV channel and the distributor consists of a simple fixed fee rather than a two-part tariff.

In this article, I present an economist’s perspective on the TV industry and view it as a so-called two-sided market, with advertisers on the one side benefiting from the presence of TV viewers and TV viewers on the other side having a dislike for advertising on TV. I use this framework to discuss the likely future development of pay TV, in particular how a future increase in competition in the TV industry will affect the prevalence of pay TV over advertising-financed TV.

We present arguments for treating health insurance and disability insurance in an integrated manner in economic analysis, based on a model where each individual's utility depends on both consumption and health and her income depends on her earning ability. When purchasing insurance, she may choose a contract that offers less than full medical treatment. We find that high-ability individuals demand full recovery and equalize utility across states, while low-ability individuals demand partial treatment and cash compensation and suffer a loss in utility if ill. Our results carry over to the case where health states are not observable.
