We develop a model that relates self-control and conflict identification to cooperation patterns in social dilemmas. As predicted, we find in a laboratory public goods experiment a robust association between stronger self-control and higher levels of cooperation. This means that there is evidence for an impulse to be selfish and that cooperative behavior requires self-control effort. Free-riders differ from other contributor types only in their tendency not to have identified a self-control conflict in the first place.

Post-grant validity challenges at patent offices rely on the private initiative of third parties to correct mistakes made by patent offices. We hypothesize that incentives to bring post-grant validity challenges are reduced when many firms benefit from revocation of a patent and when firms are caught up in patent thickets. Using data on opposition against patents at the European Patent Office we show that opposition decreases in fields in which many others profit from patent revocations. Moreover, in fields with a large number of mutually blocking patents the incidence of opposition is sharply reduced, particularly among large firms and firms that are caught up directly in patent thickets. These findings indicate that post-grant patent review may not constitute an effective correction device for erroneous patent grants in technologies affected by either patent thickets or highly dispersed patent ownership.

We explore mortality beliefs by eliciting individual-level belief distributions for participants’ remaining lifespan. Across two independent samples, from Germany and the USA, we find that individuals – while accurately forecasting their life expectancy – substantially overestimate the likelihood of dying young (50 years) and overestimate the likelihood of reaching very old age (>100 years). In other words, the modes of the belief distributions are relatively accurate, but the tails of the belief distributions are significantly ‘fatter’ than the corresponding tails of distributions obtained from demographic data. Our results are robust to variations in belief elicitation techniques, and to assumptions underlying normative longevity forecasts. The results have implications for a range of questions of economic behavior – including intertemporal choice, consumption smoothing, saving, and risk management.

Na tentativa de extrair informação da imensidão de dados hoje colhidos de fontes internas e externas, muitas empresas estão investindo pesado em ferramentas de TI e contratando cientistas de dados. A maioria, contudo, pena para conseguir um retorno digno do esforço. Isso porque estão abordando projetos de “big data” e analítica da mesma forma que abordam qualquer outro projeto de TI, sem perceber que são dois bichos completamente distintos.

In its 100th year of existence in 2009, Borussia Dortmund (BVB) was the only German soccer club listed on the stock exchange. With three days to go before the annual shareholders’ meeting on November 24 of that year, the club's managing directors, Thomas Treß and Hans-Joachim Watzke, went through the year-end figures one more time. Although the situation had improved since 2005 when the club was on the brink of insolvency, the closing accounts once again showed a negative net income. After nine years as a publicly traded company, the BVB had to report its fifth loss, this time for €5.9 million, which added up to a cumulative loss of more than €145 million. After the passing of a century, many stakeholders were concerned about the way forward. What was the organization’s purpose? What was more important, finally making a profit and meeting shareholders' expectations, or playing for the fans and the club’s honor? What could the managing directors offer to their shareholders, who had seen the value of their shares drop from €11 at the IPO to less than €1 in November 2009?

The number of patent applications filed at the Chinese State Intellectual Property Office SIPO grew tremendously over the last decades and the SIPO has become the world's third largest patent office by 2009. In this paper, we provide an overview of the institutional background of patent examination in China. Moreover, we empirically analyze the determinants of the grant lags applicants have to expect at the SIPO. The multivariate duration analysis is based on the population of 443,533 patent applications filed at the SIPO between 1990 and 2002. The average grant lag is 4.71 years with considerable variation across 30 different technology areas. Interestingly, we find that Chinese applicants are able to achieve faster patent grants than their non-Chinese counterparts (even after controlling for various other determinants of grant lags). This might be an indication of a differential treatment of Chinese applicants which would be in violation of Art. 3 (National Treatment) and Art. 4 (Most-favored Nation Treatment) of TRIPS that has been signed by China in 2001.

We model self-control conflict as a stochastic struggle of an agent against a visceral influence, which impels the agent to act sub-optimally. The agent holds costly pre-commitment technology to avoid the conflict altogether and may decide whether to procure pre-commitment or to confront the visceral influence. We examine naïve expectations for the strength of the visceral influence; underestimating the visceral influence may lead the agent to exaggerate the expected utility of resisting temptation, and so mistakenly forego pre-commitment. Our analysis reveals conditions under which higher willpower – and lower visceral influence – reduces welfare. We further demonstrate that lowering risk aversion could reduce welfare. The aforementioned results call into question certain policy measures aimed at helping people improve their own behavior.

Using a longitudinal dataset of research collaborations over 15 years at Stanford University, we build a theory of intraorganizational task relationships that distinguishes the different factors associated with the formation and persistence of network ties. We highlight six factors: shared organizational foci, shared traits and interests, tie advantages from popularity, tie reinforcement from third parties, tie strength and multiplexity, and the instrumental returns from the products of ties. Findings suggest that ties form when unfamiliar people identify desirable and matching traits in potential partners. By contrast, ties persist when familiar people reflect on the quality of their relationship and shared experiences. The former calls for shallow, short-term strategies for assessing a broad array of potential ties; the latter calls for long-term strategies and substantive assessments of a relationship’s worth so as to draw extended rewards from the association. This suggests that organizational activities geared toward sustaining persistent intraorganizational task relationships need to be different from activities aimed at forging new ones.
