The aim of this study was to detect the seroprevalence of Crimean-Congo haemorrhagic fever virus (CCHFV) in patients with fever of unknown origin (FUO) in endemic (Kyzylorda) and non-endemic (Almaty) oblasts of Kazakhstan. Methods: Paired serum samples from 802 patients with FUO were collected. Serum samples were investigated by ELISA to detect IgG and IgM antibodies against CCHFV. Sera with suspected acute infection were further investigated by RT-PCR to detect the viral RNA. Results: IgG antibodies were detected in 12.7% of the sera from both oblasts. Acute infection was shown by IgM ELISA in four patients from Kyzylorda, with only one developing severe CCHF. Viral RNA was found by RT-PCR in the other three patients' sera. Phylogenetic analysis of partial L and S segments revealed CCHFV genotype Asia 2 and a possible reassortment between the genotypes Asia 1/Asia 2. Animal husbandry, such as working with cattle and horses, was significantly associated with CCHFV seropositivity. Conclusions: The antibodies and viral RNA detected in sera indicate that mild or even asymptomatic CCHFV infections are presented in Kazakhstan. This study describes the circulation of CCHFV in the so far non-endemic Almaty oblast for the first time. In conclusion, physicians treating patients with FUO in Kazakhstan should be aware of mild CCHF.

The volume of pollution produced by an automobile is determined by driver's behavior along three margins: (i) vehicle selection, (ii) kilometers driven, and (iii) on-road fuel economy. The first two margins have been studied extensively, however the third has received scant attention. How significant is this 'intensive margin'? What would be the optimal policies when it is taken into account? The paper develops and analyzes a simple model of the technical and behavioral mechanisms that determine the volume emissions produced by a car. The results show that an optimal fuel tax would provide drivers with appropriate incentives along all three margins and that only public information is needed for a fuel tax to be set optimally. In contrast, an optimal distance tax would require private information. Lastly, relative to the optimal fuel tax, a simple uniform fuel tax is shown to be progressive. Thus, being already deployed worldwide, a uniform fuel tax is an attractive second-best policy. These findings should be accounted for when designing new mechanisms to alleviate motor vehicle pollution.

Tougher penalties have significant, but often short-lived effects. Weaker enforcement in the aftermath of such reforms may explain the absence of long-run effects.

SUMMARY We study whether the positive effects of homeownership on political participation and social capital, found in developed market economies, extend to post‐communist countries. We use the privatization of publicly‐owned housing in post‐communist countries as an exogenous source of variation of homeownership status to identify its impact on political participation and social capital formation. We find that homeownership is strongly related to higher participation in local‐level and national elections. In post‐communist countries, homeownership is also related to higher social trust. However, the positive association between homeownership and volunteering found in developed market economies does not extend to post‐communist countries. Together, our results corroborate that homeownership is associated with positive social benefits. However, these effects are highly heterogeneous and context‐dependent.

We provide an overview of housing privatization policies and outcomes in transition economies. Our primary aim is to collect and systematize key information concerning the institutional features of housing privatization in individual countries: we identify the initial conditions, the timeframe of housing privatization and its culmination, the extent of housing privatization, who decided about its terms and conditions, who was entitled to privatize the housing, and at what price. Furthermore, using micro-data covering all transition countries, we present new estimates of the extent of housing privatization, its dynamics during the second half of the 2000s, and the resulting housing tenure structure.

I evaluate the effects of a new road traffic law in the Czech Republic that became effective on July 1, 2006. The law introduced tougher punishments through the introduction of a demerit point system and a manifold increase in fines, together with an augmented authority of traffic police. I find a sharp, 33.3 percent, decrease in accident-related fatalities during the first three post-reform months. This translates into 51 to 204 saved lives with 95 percent certainty. The decline was, however, temporary; estimates of the effects going beyond the first year are around zero. Unique data on traffic police activity reveal that police resources devoted to traffic law enforcement gradually declined and were shifted towards general law enforcement. Abstrakt Studie hodnotí efekty Zákona o provozu na pozemních komunikacích v České republice, který vstoupil v platnost 1. července 2006. Zákon přinesl tvrdší postihy řidičů pomocí zavedení bodového systému a několikanásobného zvýšení pokut, spolu s posílením pravomocí policistů ve výkonu služby. V průběhu prvních tří měsíců platnosti zákona nastal prudký, 33,3 procentní, pokles počtu smrtelných zranění. To představuje 51 až 204 zachráněných životů s jistotou 95 procent. Pokles byl však krátkodobý a odhady efektů přesahujících první rok jsou kolem nuly. Unikátní data o aktivitě dopravní policie ukazují, že prostředky pro výkon služby postupně klesaly a byly více alokovány na obecné vynucování práva.

People steal copper and other nonferrous metals to sell them to scrap yard. Simultaneously, prices at scrap yards are set by the world market. We argue that shocks in metal prices represent a quasi-experimental variation in gains from crime. This allows us to estimate the behavioral parameters of supply of offenses and test the economic theory of criminal behavior. Our estimates suggest that the long-term elasticity of supply of metal thefts with respect to the re-sale value of stolen metal is between unity and 1.5. Moreover, the system tends to equilibriate quickly-between 30 and 60 percent of a disequilibrium is corrected the following month and the monthly price elasticity estimates are around unity.
