Wage and employment effects of a wage norm : The Polish transition experience
Most transition countries used tax-supported wage norms in the early 1990's, as a part of their market liberalization programs. This paper analyses how a firm-level tax (or subsidy) on deviations from a pre-set wage norm may promote employment by rotating the labor demand curve perceived by the workers' union around the value of the norm. We derive the conditions such that it yields a positive employment effect. We test the effect of the norm on the wages on a sample of Polish firms in 1990 and 1991. The data support the role of the wage norm on the position of the perceived labor demand and the role of the tax rate on its slope.transition economies, labor market, unions, excess wage tax, employment
Innovations in Monitoring Vital Events:Mobile Phone SMS Support to Improve Coverage of Birth and Death Registration: A Scalable Solution
Civil Registration (CR) of births and deaths is an essential component of any health information system.\ud
Globally, across low income countries, CR suffers from unacceptably poor quality coverage. This Health\ud
Information Systems Knowledge Hub (HIS Hub) working paper summarises and reports the results, conclusions and outlook from a small six-month project that investigated the potential of introducing a mobile phone step into the routine CR system in a rural district in Tanzania. The project developed a computer application that could receive SMS messages—from existing basic mobile phones of community-based CR officers—and feed them directly to the District Registrar’s office and computer. The message contained the details from the birth or death notification form. The system provided instant access to notifications and automatic feedback to the Village Executive Officer (VEO) if the family that experienced the birth or death event failed to register the event for certification. It also prompted the VEO to follow up with the family by conducting a questionnaire, administered by mobile phone, to determine and communicate the reasons for the non-registration. The District Civil Registrar was also able to monitor trends in these notifications via a user-friendly webbased browser and dashboard. The system was tested for six months and validated against an independent prospective household surveillance system that monitors pregnancies, births and deaths in the same period. In summary, the findings showed that the routine CR system notified only 28% of total births in the period. Adding the SMS step increased this to 51% of births. The routine CR system notified only 2.1% of deaths in the period. Adding the SMS step increased this to 14% of deaths. The SMS step therefore made significant improvements in the notification step (and modest improvements in the registration step) of routine CR. However, both notifications and registrations still fell well short of reality at community level. The most important finding of this pilot is that the current CR system in at least the study district, and likely in most of rural Tanzania, is essentially unable to provide adequate registration coverage for births and deaths, and that coverage is so low that even log order improvements are insufficient to lift it to satisfactory levels (in excess of 90%). This, as yet, says nothing regarding the quality of the data. No overwhelming reason is provided by families for the low reporting rate, suggesting that the problems are highly systemic and will need a radical redesign of CR processes to solve. To the extent that similar problems prevail in other low-income countries, it is clear that whatever these processes will be, some form of scalable real-time mobile communication such as SMS will greatly facilitate coverage levels. This pilot shows\ud
that such technology is feasible. But these results also emphasise the need for an end-to-end overhaul of the\ud
architecture and processes of how CR systems are built and integrated into the information fabric of a country. Small incremental technical fixes will not suffice\u
TCPSnitch: Dissecting the Usage of the Socket API
Networked applications interact with the TCP/IP stack through the socket API.
Over the years, various extensions have been added to this popular API. In this
paper, we propose and implement the TCPSnitch software that tracks the
interactions between Linux and Android applications and the TCP/IP stack. We
collect a dataset containing the interactions produced by more than 120
different applications. Our analysis reveals that applications use a variety of
API calls. On Android, many applications use various socket options even if the
Java API does not expose them directly. TCPSnitch and the associated dataset
are publicly available.Comment: See https://www.tcpsnitch.or
Innovations in Monitoring Vital Events: A scalable Intervention Using Mobile Phone SMS Support for Vital Registration Coverage\ud
Dynamics and monetary policy in a fair wage model of the business cycle
We first build a fair wage model in which effort varies over the business cycle. This mechanism decreases the need for other sources of sluggishness to explain the observed high inflation persistence. Second, we confront empirically our fair wage model with a New Keynesian model based on the standard assumption of monopolistic competition in the labor market. We show that, in terms of overall fit, the fair wage model outperforms the New Keynesian one. The extension of the fair wage model with lagged wage is judged insignificant by the data, but the extension based on a rent sharing argument including firm’s productivity gains in the fair wage is not. Looking at the implications for monetary policy, we conclude that the additional trade-off problem created by the inefficient real wage behavior significantly affects nominal interest rates and inflation outcomesEfficiency wage, effort, inflation persistence, monetary policy
