Technology transfer via foreign patents in Germany, 1843–77

This article analyses the spread of innovation in mid‐nineteenth‐century Germany using foreign patents as an indicator for technology transfer. It introduces a new dataset of over 1,400 patents granted in the Grand Duchy of Baden between 1843 and 1877. The data show that Baden's technology import via foreign patents from German and non‐German inventors was important. This technology transfer was broadly based, although technologies related to the textile and machine‐building industries are prominent in the data. The decision to file a patent in Baden was driven by competition and the risk of imitation. Using a gravity model with city‐level data, we find evidence that technology transfer through patents reflected existing trade links. The strong correlation between technologies filed by foreigners and domestic inventors provides further evidence that the risk of imitation fostered patent‐based technology transfer during the mid‐nineteenth century. Furthermore, we show that foreigners filed patents predominantly in industries that accounted for a high share of the workforce in Baden.     

Is brain hemisphericity a correlate of performance in problem-solving courses? A case study from an HBCU

The authors set out to determine the brain dominance characteristics of students enrolled in business statistics courses in a historically Black university in a major southeastern Texas city. Thereafter, the authors investigated the relationship between a student’s brain hemispheric preference and academic performance in college courses, which emphasize problem solving. The results reported in this study reveal that left brain– and right brain–dominant students are at parity when it comes to performance in a problem-solving course. Moreover, both left brain– and right brain–dominant learners perform better than whole-brain dominant learners in a problem-solving course.     

Gas storage valuation under limited market liquidity: an application in Germany

Natural gas storages may be valued by applying real options theory. However, it is crucial to take into account that most evolving gas markets, like the German spot market, lack liquidity. This implies that large-scale operation of storages reduces the achievable operating margin since storage operators will pay higher prices for injected gas and earn less on withdrawn gas. Optimal storage operation will take this into account. In this context, considering storage operators as price takers does not account for interdependencies of storage operations and market prices. This paper offers a novel approach to storage valuation taking into account the effect of management decisions on market prices. The methodology proposed within this paper determines the optimal production schedule and value by determining the stochastic differential equation describing the storage value and then applying a finite difference scheme. We find that limited liquidity lowers the storage value and reduces withdrawal and injection amounts. Further, we observe decreasing reservation prices for injection and withdrawing for growing illiquidity resulting in a left shift of injection and withdrawing threshold prices.     

Predictability and Persistence of the Price Movements of the S&P/Case-Shiller House Price Indices

This paper examines persistence in price movements and predictability of the US housing market both on a local level across 20 cities in the US and on a nationwide level. We use a time series approach instead of often applied multivariate approaches to exclude potential biases across local markets and provide trading strategies to compare predictability across markets and to test whether or not the detected persistence can be exploited by investors to earn excess returns. The results from the monthly and quarterly transaction-based S&P/Case-Shiller house price indices from 1987 to 2009 provide empirical evidence on strong persistence. This is confirmed by both parametric and non-parametric tests for nominal and real house prices based on expected inflation. Furthermore, the empirical findings suggest that investors might be able to obtain excess returns from both autocorrelation-based and moving average-based trading strategies compared to a buy-and-hold strategy, although the results depend on the transaction costs individual investors face.     

Earning Curves and Wage Curves

Using British county data for full-time male manual workers we extend earlier work to investigate wage and earning curves. We distinguish between total earnings and hourly wages for standard hours, uncontaminated by overtime premium. Using data from 1980–1995 we find that earnings behaviour is dominated by volatile hours in the short run, while wage growth is highly sensitive to the level of unemployment as in the classical Phillips curve with macro data. Macro evidence for sticky wages is thus confirmed at the local level, and the wage curve of rapid adjustment is rejected for normal hourly wages.     

Innovation,Creativity and Success

This article explores the role of innovation in small and medium sized firms, in relation to the firm's success. After a discussion of the relationship between success, innovation and creativity, some possible backgrounds of creativity and innovation are presented. For one part these are of a personal nature, like the entrepreneur's values, attitudes and level of education. For another part they concern institutional aspects of the firm.After the development of a number of hypotheses these are empirically checked with data from a survey among 200 entrepreneurs in six countries. In the appendices some details of the data and variables may be found.     

Digitalisierung im Gesundheitswesen — zwischen Datenschutz und moderner Medizinversorgung

The digital transformation of the healthcare branch is important and unstoppable. The enormous possibility of digitalisation to redesign and enhance processes has been shown in other branches. Digital technologies offer the similarly large potential to improve the quality and efficiency of healthcare services. However, in terms of digitalisation, the German health system lags behind other European countries. But given a lack of available evidence, the effects of the digitalisation of the healthcare system cannot be reliably evaluated. Digital access to patient data necessitates constructive error cultures in organisations in order to limit defensive medicine. And digital access to health information necessitates individual competence in searching and using this information for participatory decision-making. As with all technological progress, information security is very important in order to gain citizens’ confidence in a digital healthcare system. Thus, it is necessary to simultaneously pursue both enhanced privacy standards and state-of-the-art medical technology.
