Bremen Papers on Economics & Innovation
Although repression against elites is a common occurrence in authoritarian regimes, we know little about which elites are targeted. This paper uses an original dataset on the prosecution of mayors in large Russian cities to examine the factors that make elites more likely to be arrested.We argue that in electoral authoritarian regimes like Russia, regime leaders are reluctant to arrest popular officials. Such officials command political capital that is useful to the regime, and arrests of prominent officials can produce popular backlash. We examine this argument using an original dataset on all arrests of municipal leaders in Russia’s 221 largest cities between 2002 and 2018. We find that mayors who won their elections by large margins are less likely to be arrested. In addition, we demonstrate several other substantively important patterns: 1) a mayor’s professional background is not related to the likelihood of arrest, 2) opposition mayors are four times more likely to be arrested, and 3) arrests are more likely in ethnic republics.
The income inequality hypothesis (IIH) predicts that income inequality itself is the major determinant of population health. A novel continuous wavelet approach allows us to directly estimate the association between health and income inequality for the U.S. between 1941 and 2015 simultaneously, at any frequency and time domain. After controlling for gender, aggregate income, governmental spendings on health and education, the paper finds, first, that the frequency domain is relevant for identifying any relationship between health and income inequality, but, second, the overall evidence for the IIH is weak. Only for the time span 1956-1993 and for long-run frequencies, we find that an increase of income inequality has adverse effects on health. We are not able to confirm the existence of the IIH for any other time periods at different frequencies, even not for the period of the recent financial crisis. Hence, the empirical confirmation of the IIH is the rare exemption rather than the rule and its existence, at least on an aggregate level, clearly depends on the frequency domain.
In this article, we examine how investor motives affect investment behavior in equity crowdfunding. In particular, we compare the investment behavior of sustainability-oriented with ordinary crowd investors on six leading equity crowdfunding platforms in Austria and Germany and investigate whether they suffer from a default shock that was recently identified by Dorfleitner et al. (2019). In general, we find evidence of a default shock in equity crowdfunding that occurs immediately after the event or if investors experience more than two insolvencies. Moreover, we find that sustainability-oriented investors pledge larger amounts of money and invest in more campaigns than ordinary crowd investors. The results also suggest that sustainability-oriented crowd investors care about non-financial returns, as they react more sensitively after experiencing a default in their equity crowdfunding portfolios, which indicates that they suffer beyond the pure financial loss. These findings contribute to recent literature on equity crowdfunding, socially responsible investing, and how individual investment motives and personal experiences affect investment decisions.
Are investors in electoral authoritarian regimes discriminated against for political activism? In this paper, we implement a simple experiment to test whether affiliation with the ruling party or the political opposition affects the probability that investors receive advice from investment promotion agencies in Russian regions. Between December 2016 and June 2017, we sent 1504 emails with a short question and a number of randomized treatments to 188 investment promotion agencies in 70 Russian regions. Although investment promotion agencies are nominally depoliticized in Russia, we find that switching the political affiliation of a potential investor from the opposition party “Yabloko” to the government party “United Russia” on average increases the chances to receive a reply by 30%. The effect strongly depends on regional levels of political competition, with higher levels of discrimination in regions that are less politically competitive.
Radical innovations by definition have a great influence on the future of the existing economic systems. It means that not only radical innovators, but also other stakeholders can experience their impact. The factors, influencing the direction and strength of this impact are far from being understood. Early appropriation of radical innovator’s knowledge may be especially important for small and medium-sized firms (SMEs), serving as the source of competitive advantage. Here different proximity dimensions (geographical, cognitive, institutional, organizational and social), measuring respective distances to a radical innovator, may play a crucial role. Thus, this paper opts at revealing the importance of proximity measures for the case of German biotechnology SMEs. A longitudinal dataset covering the period from 1996 to 2016 for the innovative performance of SMEs, that are citing radical innovators, is used as the base of the analysis. Results only partially confirm the findings of previous research by indicating the negative effect of higher distance and organizational proximity. However, the effect of both cognitive and social dimension could not be confirmed. Reasons for that potentially lie both in unique character of radical innovation and peculiarities of the biotechnology field in Germany.
During the past decade, equity crowdfunding (ECF) has emerged as an alternative funding channel for startup firms. In Germany, the Small Investor Protection Act became binding in July 2015, with the legislative goal to protect investors engaging in this new asset class. Since then, investors pledging more than 1,000 EUR now must self-report their income and wealth. Investing more than 10,000 EUR in a single ECF issuer is only possible through a corporate entity. We examine how the Small Investor Protection Act has affected investor behavior at Companisto, Germany’s largest ECF portal for startup firms. The results show that after the new law became binding, sophisticated investors invest less on average while casual investors invest more. Moreover, the signaling capacity of large investments has disappeared.
This paper relates cultural evolution theory and social learning dynamics to induced preference change in consumption behavior. We argue that the promotion of sustainable consumption via preference change is a cornerstone of future policy and should complement standard regimentations such as regulation for harm reduction in production and the investment in green technologies. The application of cultural evolution mechanisms may act as a key element for implementing future societal acceptance of responsible individual consumption and a trigger for the self-transformation of the economy. We will discuss what kind of policies can be used in future to channel our consumption preferences and build up an economic “presents for the future” scenario that will go beyond existing policy tools. An already established tool in behavioral economics that provides an elegant, cheap and often effective measure to promote green behavior is “green nudging.” However, it comes at the cost of being perceived as paternalistic and non-transparent. In addition, nudging requires the alteration of a very specific choice architecture for every single consumption decision scenario and is therefore limited in its scope of application and – most importantly – long-term effectiveness. Here we offer a more general behavioral approach for future environmental policy. We argue that preference change for consumption can be induced by policy makers using tools drawn from cultural evolution. We develop concrete scenarios for policy makers to induce pro-environmental preferences within consumer populations. We argue that our approach is likely to induce alteration of existing and the establishment of new consumption patterns on a much larger scale than nudging and will be more successful in establishing permanent future effects.
This paper relates cultural distance and governance structures. We suggest a model of cultural evolution that captures the idiosyncratic socialization dynamics taking place in groups of communicating and interacting agents. Based on these processes, cultural distance within and between groups or organizational units develops. Transaction cost theorists associate higher cultural distance with higher transaction costs. Therefore, one problem of economic organization is assessing alternative governance structures in terms of the socialization dynamics they enable that entail di erent intraorganizational transaction costs. We assume that transaction can be organized within governance structures that allow transaction cost economizing socialization processes.
This paper aims to explain the emergence and diffusion of novel combinations in Germany. On the one hand, it scrutinizes on the effect of internal technological diversity. On the other hand, it looks at interactions with other actors and assesses whether relatedness to the overall regional knowledge base or rather being related to specific regional actors improves radical inventive activity in German organisations. It is demonstrated that the emergence of radical novelty is positively influenced by an optimal degree of internal diversity as well as relatedness to actors at the technological frontier. However, for this radical novelty to diffuse, rather diverse actors and cognitive proximity to the regional knowledge base is important. The results call for a more fine-grained picture in the relatedness debate and deliver interesting insights for inventive organisations in terms of partner choice and policy-makers for future initiatives.
Decline and break-up of institutionalized cooperation, at all levels, has occurred frequently. Some of its concomitants, such as international migration, have become topical in the globalized world. Aspects of the phenomenon have also become known as failing states. However, the focus in most social sciences has been on institutional emergence and persistence, not collapse. We develop an endogenous explanation of collapsing institutions. Collapse may be an implication of the very economic success of institutionalized cooperation and of increasing system complexity, when cognitive conditions for effective collective decision-making do not proportionately evolve. Moreover, we show that collapse is not a simple logical reverse of emergence. Rather, institutions break up at different factor constellations than the ones prevailing at emergence. We approach endogenous institutional break-up and its asymmetry from various paradigmatic and disciplinary perspectives, employing psychology, anthropology, network analysis, and institutional economics. These perspectives cover individuals, groups, interaction-arenas, populations, and social networks.
Radical innovations are of key importance from an economic point of view since they bear the potential to trigger the emergence of new technological trends and fuel economic prosperity while simultaneously causing far-reaching structural change processes. In this paper we focus on the transfer channels of radical innovations launched by small and medium-sized firms (SMEs). Based on a unique longitudinal dataset covering the observation period 1996 - 2016, we identify and trace back radical innovations of SMEs in the German Biotech in order to analyze the extent to which SMEs themselves or eventually also other organizations in their direct cooperation surrounding benefit from radical innovations in terms of subsequent innovation performance. Results from panel data count models indicate that direct cooperation partners of “radical innovators” generally seem to show higher innovative performance than partners of the control group, i.e. not radical innovating “statistical twin” firms. A more differentiated picture emerges if one considers the geographical and technological proximity of the cooperation partners.
Nowadays environmental and climate issues have brought the topic of bioeconomy to the political agenda around the world. Plant-based bioeconomy (pBE) has a key role in securing sustainable supplies of energy, food and raw materials for increasingly aging and growing societies. However, the technological roots and development path of pBE are far from being fully understood. Accordingly, we seek to contribute to an in-depth understanding of how biotechnology innovations affected the emergence of bioeconomy by exploring the technological field evolution of plant-based patent applications between 1995 and 2015 in Germany. We employ patent citation data and conduct forward citation analysis to trace technological trajectories within plant-based biotechnology. We extend previous work by combing patent-based citation analysis with text-mining approach. Main path analysis allows the identification of main players within plant-based biotechnology over time. Our explorations reveal dominant and also peripheral technologies within the sphere of plant-based applications and provide us in this way with a more comprehensive understanding of the field´s technological evolution. Our findings suggest a transition from basic biotechnological research towards more sustainability- and medicine-related technological orientation in the field.
This paper focuses on the question whether or not a reduction of the knowledge barrier is good for welfare. Based on a dynamic monopoly setting with simultaneous investment decisions in process as well as in product Research & Development (R&D), we show that a reduction of the knowledge barrier has ambiguous welfare consequences: Due to a lower knowledge barrier, product quality and welfare increase in the short-run. However, this may not necessarily be the case in the long-run. One reason is that a positive long-lasting knowledge barrier shock triggers the monopolist to sub-optimally lower its product R&D investments today and in the future at the cost of future product quality. This in turn may reduce welfare. Accordingly, to realize the first-best level of product quality, the long-run optimal R&D subsidy rate for product innovations increase with a reduction of the knowledge barrier.
The tendency of industries to cluster in some areas and possible effects of this regional clustering have fascinated researchers from multiple disciplines alike. Driven by the success of some clusters, as for example Silicon Valley, the concept has also become quite popular among politicians. Despite the already substantial financial support, a positive cluster effect on the success of the corresponding companies has not been consistently asserted yet. In this context, recently it has been accentuated to further examine the role of contextual influences that might explain the ambiguous effect of clusters on firm´s success. The aim of this paper is therefore to investigate the alleged effect of clusters on firm performance and the moderating influence of the specific context by conducting a meta-analysis of the relevant empirical literature. Therefor four different performance variables from four separate publication databases are considered. After the selection and exclusion process, the final sample of the meta-analysis consists of 168 empirical studies. The statistical integration of the corresponding results of these empirical studies indicate that there exists relatively weak evidence for a pure firm-specific cluster effect. Instead, it can be asserted that several variables from different levels of analysis directly or interactively moderate the relationship between clusters and firm´s success. For example, it is pointed out that the probability for a positive firm-specific cluster effect is significantly higher in high-tech industries as well as for small and medium-sized companies. Depending on the specific conditions, clusters can therefore be blessing and curse at the same time.
This paper deals with the question as to whether technology can lessen the problem of scarce resources. Focusing on fossil and biomass materials as important resources for production and consumption, the paper empirically investigates whether environmental innovations reduce the material usage in European economies. A dynamic panel model is employed to estimate the effect of environmental innovations on the use of fossil and biomass materials. It shows that there is no continuously mitigating effect of green technology. For biomass, no significant technology effects are found. Fossil materials are saved by innovations in recycling as well as by new production and processing technologies, but not by all categories of relevant green technology.
We investigate the question on how to use a non-renewable resources efficiently in the presence of a minimum subsistence level of consumption. In our model, households are characterized by Stone-Geary preferences and output is Cobb-Douglas using physical and human capital as well as resources as input factors. This setup gives rise to a six dimensional dynamic system with three control and three state variables. Despite this complexity, it is shown that a closed form solution exists in terms of the Gaussian hypergeometric function. The closed form solution allows us to calibrate the model to the situation of 108 countries using data from the World Bank on countries’ endowments with physical capital and natural resources. We are able to quantify the implications of observed capital stocks for the growth perspective of each country. In particular, we analyze whether a level of subsistence consumption equivalent to the World Bank’s poverty lines can be accomplished. Our calibration results also shed some light on what has been termed the “resource curse”.
This paper discusses automation embedded into a standard growth model without exogenous growth when investment decisions for physical and automation capital are irreversible. The imposed non-negativity constraints on physical and automation capital induces an imbalance effect between the growth rate of output and the fraction between physical and automation capital. The paper shows that this imbalance effect leads (i) to transitional dynamics off the steady state while (ii) retaining per-petual growth of the AK style in the steady state without exogenous technological progress. We also show that the resulting transition path does not have to be on the saddle path of the system without the nonnegativity constraints.
This paper investigates the response of CO2 emissions to the business cycle for the U.S. on a monthly basis between 1973-2015. Using a rolling-regression approach, we find that the emissions elasticity with respect to GDP is not constant over time, irrespective which filtering method, such as the Hodrick-Prescott, the Baxter-King, the Christiano-Fitzgerald or the Butterworth filter has been employed. In order to check whether or not emissions react differently during normal and recession times, next, we employ a Markov-switching approach. We find, first, that emissions are significantly more elastic during recessions than in normal times. Second, depending on the filtering method, we also obtain parameter estimates of the emissions elasticity above one in recession times and below one in normal times. The results are also robust against including monetary policy also in times of the zero lower bound. Thus, environmental policy instruments not turning out to be sub-optimal should account for this asymmetric response of emissions due to changes in GDP.
Humans are an ecologically extremely successful species. Underlying this achievement is our evolved unique adaptation for culture. Moreover, humans’ cultural capacity initiated a process of gene-culture coevolution that lead to a plethora of behavioral and cognitive dispositions on which cultural adaptation to challenging environments via cultural evolution rests. These characteristics of human cognition are highly relevant to any discipline dealing with human behavior. This article presents these outcomes of human phylogeny and discusses this naturalistic perspective’s implications for (evolutionary) economics. Moreover, some fruitful applications of cultural evolution theory to the explanation of economic phenomena are provided.
