Financial system, innovation and regional development: a study on the relationship between liquidity preference and innovation in Brazil

This paper discusses and assesses the features of the Brazilian Financial System, as well as the impacts of Liquidity Preference on Credit and Regional Development in Brazil. Precisely, we test the relationship between credit and development, and the role of banks in regional development. We estimate a panel across states in Brazil in order to test the impact of liquidity preference and other financial variables on Brazilian states credit level. We have also tested the relationship between liquidity preference and other financial variables across states and the number of patents, aiming at testing the importance of technology and innovation on regional development by means of bank system. Conclusions confirm both hypotheses.Monetary System, National Innovation System, Credit

Financial system, innovation and regional development: a study on the relationship between liquidity preference and innovation in Brazil

This paper discusses and assesses the features of the Brazilian Financial System, as well as the impacts of Liquidity Preference on Regional Development in Brazil. In the post-Keynesian literature, money is considered endogenous to the economic system, introduced in the economic activity through the credit provided by banks. Taken as non-neutral, banks are economic agents which can present lower or higher liquidity preference. Because of that, banks are also particularly important to the development process. Precisely, we tested the influence of credit and the role of banks in regional development. We estimate a panel across states in Brazil in order to test the impact of liquidity preference and other financial variables on Brazilian states’ number of patents, aiming at testing the importance of the bank system to technological progress and regional development. Conclusions confirm both hypotheses.Monetary System, National Innovation System, Credit, Brazil

Shocking the Crowd: The Effect of Censorship Shocks on Chinese Wikipedia

Collaborative crowdsourcing has become a popular approach to organizing work across the globe. Being global also means being vulnerable to shocks -- unforeseen events that disrupt crowds -- that originate from any country. In this study, we examine changes in collaborative behavior of editors of Chinese Wikipedia that arise due to the 2005 government censor- ship in mainland China. Using the exogenous variation in the fraction of editors blocked across different articles due to the censorship, we examine the impact of reduction in group size, which we denote as the shock level, on three collaborative behavior measures: volume of activity, centralization, and conflict. We find that activity and conflict drop on articles that face a shock, whereas centralization increases. The impact of a shock on activity increases with shock level, whereas the impact on centralization and conflict is higher for moderate shock levels than for very small or very high shock levels. These findings provide support for threat rigidity theory -- originally introduced in the organizational theory literature -- in the context of large-scale collaborative crowds

Gyne and drone production in bombus atratus (Hymenoptera: Apidae)

For over a decade, our research group has studied the biology of the native bumblebee, Bombus atratus, to investigate the feasibility of using it to pollinate crops such as tomato, strawberry, blackberry and peppers. Traditionally, captive breeding has depended on the use of captured wild queens to initiate the colonies. The goal of the current work is to investigate conditions required to produce new queens and drones in captivity. In this study, 31 colonies were evaluated under either greenhouse or open field conditions over a 15 month period. A total of 1492 drones (D) and 737 gynes (G, i.e., virgin queens) were produced by all colonies, with 16 colonies producing both drones and gynes (D&G), 11 producing only drones (D) and 4 producing neither. Some of the D&G colonies had more than one sexual phase, but no colonies produced exclusively gynes. More drones and fewer gynes were produced per colony under greenhouse conditions with the highest number of drones produced by D&G colonies. The numbers of immature stages per cell declined in colonies as increasingly more resources were allocated to the production of gynes and the maintenance of increased nest temperature

Cognitively-inspired Agent-based Service Composition for Mobile & Pervasive Computing

Automatic service composition in mobile and pervasive computing faces many challenges due to the complex and highly dynamic nature of the environment. Common approaches consider service composition as a decision problem whose solution is usually addressed from optimization perspectives which are not feasible in practice due to the intractability of the problem, limited computational resources of smart devices, service host's mobility, and time constraints to tailor composition plans. Thus, our main contribution is the development of a cognitively-inspired agent-based service composition model focused on bounded rationality rather than optimality, which allows the system to compensate for limited resources by selectively filtering out continuous streams of data. Our approach exhibits features such as distributedness, modularity, emergent global functionality, and robustness, which endow it with capabilities to perform decentralized service composition by orchestrating manifold service providers and conflicting goals from multiple users. The evaluation of our approach shows promising results when compared against state-of-the-art service composition models.Comment: This paper will appear on AIMS'19 (International Conference on Artificial Intelligence and Mobile Services) on June 2

Restrição orçamentária e lei de responsabilidade fiscal: um estudo para Minas Gerais (1995-2005)

Several institutional changes in the last 20 years have imposed to the public administrators the adoption of several policies intended to qualify the State for the new economic order. The expenditure control has turned to be central in the political economy. Regarding the Brazilian states, a dynamic of successive deficits was reverted through the renegotiation of the states debts, as well as the advent of the Fiscal Responsibility Law. This paper aims at analyzing the public finance of the State of Minas Gerais from 1995 to 2005, highlighting the impacts of the above-cited law considering its implications over the federalism in Brazil.decentralization, public debt, federalism
