The role of human capital and innovation in economic development: evidence from post-Malthusian Prussia

The effect of human capital on growth involves multiple channels. On the one hand, an increase in human capital directly affects economic growth by enhancing labor productivity in production. On the other hand, human capital is an important input into R&D and therefore increases labor productivity indirectly by accelerating technological change. In addition, different types of human capital such as basic and higher education or training-on-the-job might play different roles in both production and innovation activities. We merge individual data on valuable patents granted in Prussia in the late nineteenth-century with county-level data on literacy, craftsmanship, secondary schooling, and income tax revenues to explore the complex relationship between various types of human capital, innovation, and income. We find that the Second Industrial Revolution can be seen as a transition period when it comes to the role of human capital. As in the preceding First Industrial Revolution, “useful knowledge” embodied in master craftsmen was related to innovation, especially of independent inventors. As in the subsequent twentieth century, the quality of basic education was associated with both workers’ productivity and firms’ R&D processes. In a final step, we show that literacy had also a negative effect on fertility which increased with innovation. In general, our findings support the notion that the accumulation of basic human capital was crucial for the transition to modern economic growth.     

Cost-effective service excellence

This article integrates relevant literature to develop a conceptual model on the potential avenues to achieve service excellence at low unit costs, which we term cost-effective service excellence (CESE). To gain a deeper understanding of these strategies, their applicability and interrelatedness, we analyze how 10 organizations have achieved CESE. Our findings show that CESE can be achieved through three core strategies. First, a dual culture strategy provides a comprehensive set of high-quality services at low cost, largely driven by leadership ambidexterity and contextual ambidexterity. Second, an operations management approach reduces process variability and thereby allows the increased use of systems and technology to achieve CESE. Third, a focused service factory strategy can enable CESE through a highly specialized operation, typically delivering a single type of service to a highly focused customer segment. The use of the three approaches ranges from “pure” (e.g., mostly pursuing a dual culture strategy) to combinations of the latter two approaches with the dual culture strategy (e.g., a focused service factory strategy combined with dual culture). Our conceptual model provides an integrated view of the strategic options available to organizations that aim to pursue a strategy of CESE.     

A Descriptive Model of Banking and Aggregate Demand

We integrate a banking sector into an accessible macroeconomic framework, which then provides new insights on developments around the Global Financial Crisis. The analysis shows that growth of banking sector money supply may help explain the secular decline in long-term interest rates before the crisis. A new bank funding channel of monetary transmission clarifies why increases in central bank policy rates could not reverse this trend. Our analysis highlights the distinction between the zero lower bound and the liquidity trap, and shows that bank recapitalizations can be more effective than fiscal expansions in restoring aggregate demand after a banking crisis.     

Consumer cheating on service guarantees

Fear of opportunistic customers is an important reason why firms are reluctant to implement service guarantees. This article empirically tests potential drivers of cheating. Potential material gain and repeat purchase intent were tested across three studies, whereas satisfaction, ease of invoking the guarantee, morality, shame, self-monitoring, and Machiavellianism were each tested in a subset of the three studies. The results for potential material gain and repeat purchase intent were consistent across all three studies: potential material gain had no effect on consumer cheating, but repeat purchase intent reduced that tendency. Other findings suggest that high levels of satisfaction, morality, and self-monitoring reduce cheating, whereas high levels of Machiavellianism increase cheating. Furthermore, two three-way interaction effects were encountered. Specifically, Machiavellianism interacted with gain and ease of invocation, and with gain and repeat purchase intent. In both cases, individuals with high Machiavellianism took advantage of certain situational constellations.

The Foreign Exchange Rate Exposure of Nations

Following the well-known approach by Adler and Dumas (Financ Manage 13(2):41–50, 1984), we evaluate the foreign exchange rate exposure of nations. Results based on data from 27 countries show that national foreign exchange rate exposures are significantly related to the current account and financial account balance variables of corresponding economies.
