Productivity,employment and labor demand in Polish industry in the 1980s: Some preliminary results from enterprise-level data

The paper uses annual data from a panel of 334 Polish industrial enterprises over the period 1983–1988 to test empirically a simple neoclassical approach to the socialist labor market. First, an enterprise production function is estimated. The paper finds that for most enterprises, the resulting estimated marginal product of labor exceeds the wage paid by the enterprise by a considerable margin, suggesting general excess demand for labor. The paper then looks at how the difference between the MPL and the wage is related to the rate of change of employment, and finds that firms where the MPL is higher than the wage — firms which in a neoclassical model would have a large excess demand for labor — do not shed labor any more slowly than other firms.     

Teleological Interpretation and Land Law

It may also be presumed that contracts for the sale or other disposition of an interest in land (including leases) fall outside [the] provisions of [the Unfair Terms in Consumer Contracts Directive] (Chitty on Contracts, 27th ed, 1994, vol 1, at 14–091).     

Determination of paraquat from formalin-fixed tissue

In this paper, a sulfuric acid digestion method and a clean-up technique by using cation exchange resin followed by XAD-2 resin has been developed for the determination of paraquat from formalin-fixed tissue at the submicrograms per gram level. Formalin-fixed tissue is dissolved by hot sulfuric acid, then paraquat is isolated and purified with cation exchange chromatography. The eluted paraquat forms an ion-pair with sodium dodecyl sulfate, it is then adsorbed on XAD-2 resin. Paraquat is eluted, extracted and reduced with solvent mixtures, NaCl solution and dithionite reagent, respectively. The calibration graphs of zero-order and second-derivative spectroscopy are linear in the range of 0.01-5.0 mg/kg. The relative standard deviation was less than 5% and the detection limit was 0.02 mg/kg based on 0.5-g samples. The sensitivity of the proposed method could be increased by using larger sample sizes. The method was precise and gave a quantitative recovery of paraquat spiked into formalin-fixed liver homogenates (78%). The proposed method has been satisfactorily applied to the determination of paraquat in the formalin-fixed tissues of suspected poisoned cases. It has been shown to be of great value in the field of forensic toxicology especially when formalin-fixed tissue only is available.     

Opaque rather than transparent: Why the public cannot monitor monetary policy

Federal Reserve officials and many observers of monetary policy claim that the implementation of monetary policy has become more “transparent” over the last decade. This paper argues that monetary policy is anything but transparent because multiple and conflicting goals for monetary policy still exist, precise targets for these goals never are defined, the Fed’s economic model is unknown to the public and, by confusing its apparent intermediate target variable with its true policy instrument, actions taken to be stimulative can be contractionary and vice versa.     

Unusual suicides with chain saws

Two cases of suicide with bandsaws, undertaken by workers in carpenters' workshops are reported and discussed. Their choice of this method was based on the fact that they knew how dangerous such machines were. Both cases were watched by witnesses, who could not intervene due to the speed of the events. It was possible to exclude accident or homicide.     

Fatigue in multiple-car fatal accidents

In a re-examination of 334 fatal multiple car accidents, without any reasonable explanation besides possible intoxication, 205 drivers were found responsible for the accident. Twenty-one of these accidents happened between midnight and 0600 h and 11 of the drivers were found to be intoxicated with a blood/alcohol content (BAC) of more than 0.080%. The remaining 184 accidents took place during the rest of the day and 55 drivers were intoxicated. By comparing this apparent over-representation of intoxicated drivers in night-time accidents with that of a control group of no less than 15,923 drivers, it was possible to convert this over-representation into an under-representation. This decline in accidents while under influence seems to indicate another human accident factor specific to night-time traffic. It is concluded that fatigue is an overlooked but most obvious cause of otherwise unexplainable accidents in the night-time traffic.
