On the optimality of a minimum wage: New insights from optimal tax theory

We build a theoretical model to study whether a minimum wage can be welfare-improving if it is implemented in conjunction with an optimized nonlinear income tax. We consider this issue in a framework where search frictions on the labor market generate unemployment. Workers differ in productivity. The government does not observe workers' productivity but only their wages. Hence, the redistributive policy solves an adverse selection problem. We show that a minimum wage is optimal if the bargaining power of the workers is relatively low. However, if the government controls the bargaining power, then it is preferable to set a sufficiently high bargaining power.     

Debates and dissent inside the FOMC during WWII

Abstract

We demonstrate that even though during WWII the interest rate was close to zero supporting the financing of the military effort, dissent inside the FOMC occurred with a similar frequency to other policy episodes. Our analysis highlights that the debates which resulted in dissents turned around two broad issues: the size of the Fed’s balance sheet as well as the functioning of and communication with financial markets. Thus, we argue that the conventional view depicting the Fed as merely accommodating treasury needs should be revised. Our detailed investigation of dissents emphasises the modernity of the objections raised by Fed officials.     

Perceived Acceptability of Organizational Layoffs and Job Alliances During a Recession: A Mapping of Portuguese People’s Views

The present study aimed to explore and map the views of Portuguese laypersons regarding the acceptability of downsizing and restructuring measures during a recession. Two hundred and seven participants with various levels of training in economics were presented with a number of realistic scenarios depicting various measures, and were asked to indicate the extent to which they considered them to be acceptable. The scenarios were created by varying three factors likely to have an impact on people’s views: the magnitude of a company’s reduction in net sales, the magnitude of planned downsizing, and the way in which downsizing would be implemented, either through layoffs, job alliances or both. Six qualitatively different personal positions were found. Four of these following positions were expected: (1) never acceptable (15 %), (2) mainly depends on the magnitude of downsizing (22 %), (3) mainly acceptable (17 %) and (4) job alliance (8 %). Two unexpected positions were also observed: (5) drastic measures (8 %) and (6) undetermined (29 %).     

Facilitating multimodal logistics and enabling information systems connectivity through wireless vehicular networks

The adoption of information and communication technology (ICT) has made it possible to experience high levels of visibility, control and connectivity across the entire supply chain. However, in road transport logistics, wireless ICT applications like cellular networks, Wi-Fi, UMTS, 4G and WiMax have not entirely solved reliability and connectivity problems due to difficulties associated with limited range, scalability and security. This paper examines the feasibility of using a vehicular network technology, dedicated short range communication (DSRC), in a multimodal logistics environment as means of providing enhanced visibility and connectivity using a secure access architecture. The secure access architecture is necessary to provide a high degree of security to the detailed visibility involving road haulage feeding port operations using a centralised port service.     

Societal risks as seen by Chinese students living in Macao

The present study reports on mean risk magnitude judgements expressed by Chinese students living in Macao on 87 hazardous activities, substances and technologies. These judgements were compared with findings on African, American and European samples. Despite high similarity in mean results, standard deviations, and linear correlation with the other countries, Macao appears to be the country in which the level of risk perception was clearly the highest, and this seems largely due to five items connected with violence and crime. These results are explained by the exceptionally high level of crime in Macao and its crude display by the local media.     

Trends in occupational mobility in France: 1982–2009

Are labor markets more turbulent now than thirty years ago? Most job and worker flows imply that the answer is “no”, with one exception: occupational mobility, which increased substantially in the United States. This paper remedies the lack of comparable evidence by focusing on France for the years 1982 to 2009. After correcting for various statistical biases and discrepancies that affect the measurement of occupational mobility, it documents this reallocation process overall and in different subgroups. The data reveal that, over the period considered, the fraction of workers switching occupation exhibits no trend in the aggregate because changing demographics mask increases in mobility within several age and education groups. After taking these composition effects into account, occupational mobility increased sharply in France as well.
