Does European development have Roman roots? Evidence from the German Limes

This paper contributes to the understanding of the long-run consequences of Roman rule on economic development. In ancient times, the area of contemporary Germany was divided into a Roman and a non-Roman part. The study uses this division to test whether the formerly Roman part of Germany are more developed than the non-Roman part. This is done using the Limes Germanicus wall as geographical discontinuity in a regression discontinuity design framework. The results indicate that economic development—as measured by luminosity—is indeed significantly and robustly larger in the formerly Roman part of Germany. The study identifies the persistence of the Roman road network until the present as an important factor causing this developmental advantage of the formerly Roman part of Germany both by fostering city growth and by allowing for a denser road network.     

Russian enterprises at the end of 2016: Reaction to varying ruble exchange rate and the workforce situation

This article represents an analysis of and comments on the results of a regular survey of Russian enterprises operating in the real sector, which was conducted by the Institute of Economic Forecasting, Russian Academy of Sciences. It represents opinions of enterprises, the modern macroeconomic problems of which they believe to be the most acute. This article considers the responses of enterprises regarding how their activities have been affected by the mutual sanctions between Russia and Western countries, as well as by Russia’s WTO accession. We have shown the opinions of enterprises on their interests in the ruble exchange rate. This ref lects the current situation with the workforce at enterprises and gives data on their participation in solving of housing problems faced by their employees. This article contains information on how enterprises rate today’s level of competition with foreign manufacturers on Russian markets.     

Peer effects on risk behaviour: the importance of group identity

This paper investigates whether and to what extent group identity plays a role in peer effects on risk behaviour. We run a laboratory experiment in which different levels of group identity are induced through different matching protocols (random or based on individual painting preferences) and the possibility to interact with group members via an online chat in a group task. Risk behaviour is measured by using the Bomb Risk Elicitation Task and peer influence is introduced by giving subjects feedback regarding group members’ previous decisions. We find that subjects are affected by their peers when taking decisions and that group identity influences the magnitude of peer effects: painting preferences matching significantly reduces the heterogeneity in risk behaviour compared with random matching. On the other hand, introducing a group task has no significant effect on behaviour, possibly because interaction does not always contribute to enhancing group identity. Finally, relative riskiness within the group matters and individuals whose peers are riskier than they are take on average riskier decisions, even when controlling for regression to the mean.     

From Supply Chains to Supply Ecosystems: Implications for Strategic Sourcing Research and Practice

Traditionally, sourcing decisions such as what to buy and from whom to buy it were viewed as clerical in nature. Today, however, many executives view sourcing decisions as strategic and these decisions are being made from more prominent positions within firms. Indeed, over time more companies are embracing the concept of strategic sourcing—making acquisition decisions with the intent of creating value and achieving a competitive advantage. In this article, we introduce the Special Topic Forum articles on strategic sourcing and performance. Each offers important implications for strategic sourcing research and practice. An overall implication is that some traditional supply chains appear to be giving way to supply ecosystems, which represent a set of interdependent and coordinated organizations that share common adaptive challenges and that collectively shape the creation and nurturing of a sourcing base that contributes to competitive advantage and superior performance. We offer several theoretical perspectives that hold promise for explaining supply ecosystem functioning and outcomes. In terms of practice, firms need to adapt their strategic sourcing to this evolution or run the risk of being weakened.     

A tale of two civilizations in the era of Facebook and blockchain

Five billion people in the world do not have the kind of ledgers that provide the documented information that allows them to transfer, partition, and aggregate assets and talents in such a way that they can be scaled up, secure investment, guarantee credit, certify reputation, and capture abstract surplus value. The difficulty that most people have in making combinations is a major cause of global inequality and unnecessary poverty.     

Latin American earnings inequality in the long run

This paper traces between-group earnings inequality for six Latin American countries over two centuries based on wage and income series compiled from a large array of primary and secondary sources. We find that inequality varied substantially by country and by period, questioning the notion that colonial legacies largely dominated the evolution of inequality. There is a broader inequality trajectory over the long run in the form of an “m” pattern with peaks around 1880 and the 1990s and a trough around 1920/1930s. Export-led growth does not necessarily imply a rise in inequality, while the import-substitution industrialisation efforts did not translate into a more egalitarian distribution of income. More notably, Latin America’s experience does not exhibit the great inequality levelling as seen in the North Atlantic economies from the 1930s to the 1970s.
