Land Invasions,Insecure Property Rights and Production Decisions

This paper investigates empirically the effect of land invasions on farm production decisions. The main hypothesis is that more invasions in a region are associated with lower investment, and in particular a bias towards annual crops as opposed to long‐term crops. We use a county‐level dataset for the state of Paraná, Brazil, from 2003 to 2007, with 1,995 observations. The panel data structure allows us to control for fixed effects, such as the formalisation of land titles and land concentration, which might be correlated with the intensity of invasions. An instrumental variable fixed effects model was estimated to avoid other sources of bias. Our main finding is that land invasions are associated with lower long‐term crop production and a higher percentage of annual crops, which could accelerate land degradation, and undermine environmental sustainability.     

Adopt the euro? The GME approach

The objective of this paper is to evaluate the degree of financial integration achieved in the European Union based on covered interest parity and using Generalized Maximum Entropy. EU countries are divided into two groups according to their current situation with respect to the adoption of the euro. Financial integration before the adoption of the euro is analyzed for the countries that adopted the euro in 1999. Similarly, current financial integration is evaluated for non-euro EU countries. Besides the importance of comparing the situation of the non-euro EU countries with the situation of the euro EU countries previous to the euro adoption, which may be useful to evaluate an eventual decision of the non-euro members to adopt the euro, it is interesting to analyze the performance of Generalized Maximum Entropy. Generalized Maximum Entropy has the ability to estimate the parameters of a regression model without imposing any constrains on the probability distribution of errors and it is robust even when we have ill-posed problems. Overall our results suggest that the degree of financial integration on non-euro countries is lower than the degree of financial integration that existed among euro adopting countries before the adoption of the euro.     

Why are tax revenues of local governments so low?

Using a unique data set on federal grants and tax revenues of more than 5000 Brazilian cities, we find that the federal government imposes an implicit tax of almost 10% on city governments’ tax revenues: for every dollar that a city collects from its residents, the federal government withdraws grants worth 9 cents from the city. Our findings suggest that local government tax revenues are low not because federal grants crowd out tax revenues, but because tax revenues crowd out federal grants.

Is this workplace bullying? How ideas about conflict shape conflict management strategies

The adoption of specific conflict management strategies has usually been linked to various factors, such as litigation avoidance, union substitution and the pursuit of strategic benefits. This study advances the hypothesis that actors’ different frames of reference impact how workplace conflicts are interpreted and managed by unions and employers. Drawing on original data from the Brazilian banking sector, this article shows that companies and unions have different interpretations of workplace bullying. Unions understand workplace bullying as an organizational or sectoral problem inherent to labour relations in the banking sector. In contrast, employers see workplace bullying as a problem caused by individual managers. These different understandings of the same type of conflict are shaped by each actor's frame of reference and influence their responses to workplace bullying. With a pluralist or critical frame of reference, unions favour conflict management tools that try to promote structural changes in the sector. With a unitarist frame of reference, employers try to transform individual behaviour or simply remove individual managers from the workplace. Therefore, organizations with a unitarist frame interpret and respond to conflicts in notably different ways from organizations holding a pluralist or critical frame of reference.     

Economic integration,industrial structure,and catch-up growth: Firm-level evidence from Poland

We examine if and how deeper economic integration with high-income nations impacts industrial performance. We exploit Poland's accession to the EU in 2004 as a source of variation in the degree of market integration with Germany. Using data on Polish manufacturing firms in the period 1995–2013, we find that EU accession was followed by significant within-firm growth in output and productivity, notably in industries in which Germany was more specialized at the moment of accession. Increased flows of German investment to these sectors played an important role in shaping these effects.

A fuzzy model to assess the resilience of Protection and Civil Defense Organizations

Resilience is the intrinsic ability of a system to adjust its functioning prior to, during, or following changes and disturbances, so that it can sustain required operations under expected and unexpected conditions. Protection and Civil Defense Organizations (PCDOs), communities and cities deal with disaster management involving routine, non-routine and even unpredictable/unforeseen situations with varying degrees of complexity. It is important that such organizations continually assess their resilience, enable them to learn on their weaknesses and real capacities to cope with emergency situations. This research aimed the development of an Organization Resilience Indicator System (ORIS) based on a fuzzy model to enable PCDOs self-assesses their resilience. Based on a literature review on organizational and community’s resilience, a system of resilience indicators was defined. This system was validated by experts using fuzzy set theory to aggregate opinions in the development of a resilience ideal pattern. Then, the resilience of four PCDO organizations was self-evaluated. The results were accordingly to maturity level of the organizations evaluated, indicating that the ORIS is valuable to measure PCDOs resilience.     

The finance-investment and saving-funding circuit in the closed and open economies with government

This contribution discusses the Finance-Investment and Saving-Funding (FISF) circuit regarding the closed and open economies with government. Moreover, we discuss the fiscal policy effects on aggregate demand and income in the FISF circuit context. Keynes explained the FISF circuit assuming a closed economy without government. The novelty of the current contribution is to analyze the abovementioned circuit in the closed and open economy context including government. We show that the basic features of the FISF circuit remain unchanged for the closed and open economies when government is considered in the circuit.
