This paper explores the reasons why artificial or mineral sources of nitrogen, which were more readily available in Britain than in other European countries, were only slowly adopted by farmers in the decades prior to and during the First World War. It considers why nitrogen in the form of sulphate of ammonia, a by-product of coal-gas (town-gas) manufacture, was increasingly exported from Britain for use by German farmers. At the same time Britain was attempting to monopolise foreign supplies of Chilean nitrate, which was not only a valuable source of fertiliser for agriculture but also an essential ingredient of munitions production. The article also investigates the reasons why sulphate of ammonia was not more widely used to raise agricultural production during the First World War, at a time when food shortages posed a major threat to public morale and commitment to the war effort.

This paper reports the results of an experiment designed to investigate how legal regimes affect social welfare. We investigate four legal regimes, each consisting of a liability rule (strict or negligence) and a damage measure (out-of-pocket or independent-of-investment). The results of the experiment are for the most part consistent with the qualitative predictions of Schwartz's (1997) model; however, subjects' actual choices deviate from the point predictions of the model. We explore whether these deviations arise because: (1) subjects form faulty anticipations of their counterparts' actions and/or (2) subjects do not choose the optimal responses given their anticipations. We find that subjects behave differently under the four regimes in terms of anticipation errors and departures from best responses. For example, subjects playing the role of auditors anticipate investments most accurately under the regime with strict liability combined with out-of-pocket damages, but are least likely to choose the optimal response given their anticipations. This finding implies that noneconomic factors likely play a role in determining subjects' choices.

Abstract Corrupt deals are commonly arranged by intermediaries. However, attempts to deter corruption pay little attention to the role of intermediaries in corrupt deals. This paper reports a laboratory bribery experiment on corruption designed to investigate how intermediaries with information about the lowest bribe that the official is willing to accept in a briber-initiated corrupt deal affect the effectiveness of the four-eyes-principle (FEP) on deterring corruption. We find that the introduction of the FEP significantly decreases the corruption level by increasing uncertainty. However, the presence of intermediaries with information completely offsets the positive effect of introducing the FEP on preventing corruption. Our findings suggest that further research on corruption should allow a more active role of intermediaries, and legislators should take the role of intermediaries into account when designing anti-corruption mechanisms.
