Robotization and labour dislocation in the manufacturing sectors of OECD countries: a panel VAR approach

Robots are the most important innovation which has affected the production process in the last three decades. Thanks to the latest advances in technology, they have been able to perform an ever-increasing number of tasks, eventually replacing human work within the whole production process. However, because of the scarcity of suitable data, the extent of this potentially disrupting process is not fully assessed. This paper makes up for the lack of empirical evidence on the effect of robotization on labour dislocation using data collected by the International Federation of Robotics (IFR) on the number of robots installed in the different manufacturing industries of 16 OECD countries over the period 2011–2016. We show that at the industry level a 1% growth in the number of robots reduces the growth rate of worked hours by 0.16, as well as the selling prices and the real values of the compensations of employees. Moreover, we show that a given sector is more likely to be robotized when it is expanding both in terms of relative prices and employee compensations. We conclude that, at least in the selected countries, the introduction of robots plays a key role in slowing down human labour and compensation growth.     

Volatility and persistence of fluntuations: individual production series in Italy, 1890–1985

The analysis is focused on possible time-related changes in the cyclical behaviour of production using a set of individual production series. Disaggregate data are used to analyse whether short-run fluctuations have actually become less extreme or erratic in time and whether the tendency of shocks to have permanent or transitory effects has changed between the pre-war and post-war eras. A third aspect of cyclical trends examined concerns the correlation of short-term changes across sectors. The main finding of the paper is that there has been little change in the behaviour of the individual series over time in fluctuation size, persistence and frequency. Thus, a reduction in variability appears also to be due to a problem of statistical measurement. Rather then suggesting, as the standard literature does, that demand shocks were unimportant in the post-war period – which implies that supply shocks were more important – an estimate of the Italian experience gives evidence of the importance of both causes.     

Attributes Versus Benefits: The Role of Construal Levels and Appeal Type on the Persuasiveness of Marketing Messages

When should marketers emphasize attributes or benefits in their communications? Grounded in construal-level theory, the results of four studies suggest that when a purchase is planned for the distant future or when construal levels are high, benefit-based appeals are more persuasive than attribute-based appeals. By contrast, when a purchase is planned for the near future or when consumers are predisposed to low construal levels, attribute-based appeals are equally as persuasive as benefit-based appeals. However, when low construal levels are temporarily induced using a mind-set manipulation, attribute-based appeals are found to be more persuasive than benefit-based appeals. Moreover, we demonstrate how these effects occur only when processing fluency is uninhibited. This research establishes an important link between these appeal types and construal levels, subsequently demonstrating when marketers should use these appeals.     

AN ANNUAL CHAIN INDEX OF ITALY'S "REAL" PRODUCT, 1861–1989

The construction and application of a Paasche annual chain index to the Italian GDP figures between 1861 and 1989 is the subject of this article. Comparison with product at constant prices shows, except for war periods, a revaluation of GDP in favour of the annual chain index of around 0.10 percent. The most striking differences are concentrated into periods of marked changes in relative prices, and the new index modifies the temporal pattern of the growth trend by accentuating, without altering the periodization, cyclical fluctuations.     

Risky production processes and demand for preventive safety measures under uncertainty

This paper analyzes the behavior of a competitive risk-averse firm that has to choose the optimal level of labor and preventive safety measures. If the firm's injury function includes a random component, then the firm is characterized by a lower demand for labor and by a higher demand for safety measures with respect to a firm whose injury risk is completely under its control. The comparative statics show that shifts in the parameters of the risk distribution will have effects that depend on the absolute risk-aversion functions. The introduction of safety standards will prompt a reduction in the demand for labor while a tightening of the compensation system will have ambiguous effects on the demand for the two inputs.     

Indeterminacy and nonlinear dynamics in an OLG growth model with endogenous labour supply and inherited tastes

This study analyses the dynamics of a two-dimensional overlapping generations economy with endogenous labour supply à la Reichlin (J Econ Theory 40(1):89–102, 1986) and aspirations. We show that the degree of nonlinearity of consumption externality in individual utility is responsible for the existence of either one steady state or two steady states. In addition, some interesting global dynamic properties, such as cyclical behaviour and/or global indeterminacy, emerge depending on the relative importance of aspirations in utility.
