Modelo de mudança organizacional: estudo de caso no setor de compras

O presente trabalho apresenta um modelo de mudança organizacional para melhorar o processo empresarial de compra de uma construtora, proveniente do sistema de comunicação entre o escritório central e suas obras, a fim de identificar as oportunidades e deficiências existentes no sistema, seja de ordem tecnológica e/ou gerencial. O mapeamento das informações permite detectar os percursos desnecessários que impossibilitam o sistema de comunicação funcionar de forma ágil e otimizada, bem como perceber as oportunidades de melhorias contínuas ao processo. O método de pesquisa se baseou no aperfeiçoamento de processos empresariais, que consiste na modelagem do processo citado, por meio da coleta de dados, análise de documentos, desenho de fluxos de informações existentes no modelo e discussão dos resultados. Para validação da aplicação do método, fez-se o estudo de caso único em uma construtora do subsetor edificações, o qual gerou fluxogramas do processo de compras atual e proposto como modelo de mudança organizacional.

Análise de sistemas de máquinas térmicas em plantas de processos químicos

Pressure drop and energy efficiency of compressors in chemical plants are the focus of this study. Its objective is an analysis of possible sources of energy loss through the study of pressure loss in pipes, calculation of thermodynamic efficiency of the compressors. Important issues are raised for this analysis such as the types of compressors, the operating range of each compressor, compression types, as well as a study of accessories such as filters and valves. After studying these issues was carried out calculations of pressure drop step-bystep and with a software WIPCD. Followed by the calculation of efficiency of compressors and monthly energy cost of each compressor in operation. Finally, the study shows some suggestions for immediate improvements, changes and suggestions for possible future purchases of compressors

As compras coletivas como estratégia do comércio na atualidade: análise do consumo e das redes geográficas na região metropolitana de Campinas

The collective purchases translate into new business strategies that so far are poorly studied, but they have modifyied considerably the forms of consumption through the consumers individualisation, which causes changes in society's routine. The analysis of the theme was performed by study cases of collective shopping places in the city of Campinas, country of the state of São Paulo, and on its influence in the metropolitan area, which intented to understand, through custumers interviews, the contradictions and peculiarities of this service that has increased each day more . For this purpose, the research methodology is focused on the consumer , that's because the process of productive change tied to forms of trade and distribution of goods have been transforming social values considerably, based increasingly on impulsive consumming . Thus, to understand how the electronic commerce and more specifically the collective shopping websites works, it's necessary to examine the forms of commerce and the consumer's behavior in order to explain the city organization and the contradictions of the geographic space

Essays in Macroeconomics

The dissertation consists of four papers that aim at providing new contributions in the field of macroeconomics, monetary policy and financial stability. The first paper proposes a new Dynamic Stochastic General Equilibrium (DSGE) model with credit frictions and a banking sector to study the pro-cyclicality of credit and the role of different prudential regulatory frameworks in affecting business cycle fluctuations and in restoring macroeconomic and financial stability. The second paper develops a simple DSGE model capable of evaluating the effects of large purchases of treasuries by central banks. This theoretical framework is employed to evaluate the impact on yields and the macroeconomy of large purchases of medium- and long-term government bonds recently implemented in the US and UK. The third paper studies the effects of ECB communications about unconventional monetary policy operations on the perceived sovereign risk of Italy over the last five years. The empirical results are derived from both an event-study analysis and a GARCH model, which uses Italian long-term bond futures to disentangle expected from unexpected policy actions. The fourth paper proposes a DSGE model with an endogenous term structure of interest rates, which is able to replicate the stylized facts regarding the yield curve and the term premium in the US over the period 1987:3-2011:3, without compromising its ability to match macro dynamics.

Global Reuse and Optimal Waste Policy

Electronic waste generated from the consumption of durable goods in developed countries is often exported to underdeveloped countries for reuse, recycling and disposal with unfortunate environmental consequences. The lack of efficient disposal policies within developing nations coupled with global free trade agreements make it difficult for consumers to internalize these costs. This paper develops a two-country model, one economically developed and the other underdeveloped, to solve for optimal tax policies necessary to achieve the efficient allocation of economic resources in an economy with a durable good available for global reuse without policy measures in the underdeveloped country. A tax in the developed country on purchases of the new durable good combined with a waste tax set below the domestic external cost of disposal is sufficient for global efficiency. The implication of allowing free global trade in electronic waste is also examined, where optimal policy resembles a global deposit-refund system.

Unconventional Monetary Policy and the Great Recession: Estimating the Macroeconomic Effects of a Spread Compression at the Zero Lower Bound

We explore the macroeconomic effects of a compression in the long-term bond yield spread within the context of the Great Recession of 2007–09 via a time-varying parameter structural VAR model. We identify a “pure” spread shock defined as a shock that leaves the policy rate unchanged, which allows us to characterize the macroeconomic consequences of a decline in the yield spread induced by central banks’ asset purchases within an environment in which the policy rate is constrained by the effective zero lower bound. Two key findings stand out. First, compressions in the long-term yield spread exert a powerful effect on both output growth and inflation. Second, conditional on available estimates of the impact of the Federal Reserve’s and the Bank of England’s asset purchase programs on long-term yield spreads, our counterfactual simulations suggest that U.S. and U.K. unconventional monetary policy actions have averted significant risks both of deflation and of output collapses comparable to those that took place during the Great Depression.

Purchase decision-making is modulated by vestibular stimulation

Purchases are driven by consumers’ product preferences and price considerations. Using caloric vestibular stimulation (CVS), we investigated the role of vestibular-affective circuits in purchase decision-making. CVS is an effective noninvasive brain stimulation method, which activates vestibular and overlapping emotional circuits (e.g., the insular cortex and the anterior cingulate cortex (ACC)). Subjects were exposed to CVS and sham stimulation while they performed two purchase decision-making tasks. In Experiment 1 subjects had to decide whether to purchase or not. CVS significantly reduced probability of buying a product. In Experiment 2 subjects had to rate desirability of the products and willingness to pay (WTP) while they were exposed to CVS and sham stimulation. CVS modulated desirability of the products but not WTP. The results suggest that CVS interfered with emotional circuits and thus attenuated the pleasant and rewarding effect of acquisition, which in turn reduced purchase probability. The present findings contribute to the rapidly growing literature on the neural basis of purchase decision-making.

Three “Bali Deliverables” for more Food Security

As the clock is ticking for a positive outcome at the Ninth WTO Ministerial Conference to be held in Bali in December 2013, agricultural negotiators are scrambling to find solutions to issues such as tariff-rate quota (TRQ) administration and export competition in order to improve trade flows. The main issue seems to be whether WTO rules applying to public stockpiles in developing countries need to be changed or temporarily suspended as a means to enhance national food security. This paper is based on a note submitted to the ICTSD-IPC Expert Group “Meeting on Agriculture and Food Security – Policy Options for MC9 and beyond” (Geneva, June 2013). It lists the policy instruments impacting on global, national and (urban and rural) household food security – “The Food Security Tool Box” – and asks which immediate decisions the WTO Ministers might take in this field despite the political difficulties such as continued agro-dumping practices or the “land grab” issue. Three such “deliverables” are outlined: (i) regional and “virtual” food security schemes could be allowed to provide reserves to other countries without violating the obligation to “form an integral part of a food security programme identified in national legislation” (Agreement on Agriculture, Annex II, para 3); (ii) TRQ under-fills could be improved by mandatory enquiries into low fill rate situations; and (iii) World Food Program (WFP) and other non-commercial food purchases could be exempted from export restrictions and prohibitions. High ambitions for Bali seem to be misplaced. A more realistic yet real progress could restore the dwindling credibility of the WTO as a forum for trade negotiations.

After Bali: WTO Rules Applying to Public Food Reserves

Once more, agriculture threatened to prevent all progress in multilateral trade rule-making at the Ninth WTO Ministerial Conference in December 2013. But this time, the “magic of Bali” worked. After the clock had been stopped mainly because of the food security file, the ministers adopted a comprehensive package of decisions and declarations mainly in respect of development issues. Five are about agriculture. Decision 38 on Public Stockholding for Food Security Purposes contains a “peace clause” which will now be shielding certain stockpile programmes from subsidy complaints in formal litigation. This article provides contextual background and analyses this decision from a legal perspective. It finds that, at best, Decision 38 provides a starting point for a WTO Work Programme for food security, for review at the Eleventh Ministerial Conference which will probably take place in 2017. At worst, it may unduly widen the limited window for government-financed competition existing under present rules in the WTO Agreement on Agriculture – yet without increasing global food security or even guaranteeing that no subsidy claims will be launched, or entertained, under the WTO dispute settlement mechanism. Hence, the Work Programme should find more coherence between farm support and socio-economic and trade objectives when it comes to stockpiles. This also encompasses a review of the present WTO rules applying to other forms of food reserves and to regional or “virtual” stockpiles. Another “low hanging fruit” would be a decision to exempt food aid purchases from export restrictions.

Supplemental Nutrition Assistance Program: A policy analysis of restricting foods with minimal nutritional value

In 2011, expenditures for the Supplemental Nutrition Assistance Program (SNAP) reached an all-time high of $72 billion. The goal of SNAP is " to alleviate hunger and malnutrition…by increasing food purchasing power for all eligible households who apply for participation." It has been well established that proper nutrition is essential to good health, making SNAP an important program to public health consumers. Thus, this analysis examined whether SNAP is meeting its stated goal and whether the goal would be reduced if the purchase of foods of minimal nutritional value (FMNV) were restricted. ^ A review of existing literature found that SNAP has been shown to alleviate hunger, but the studies on the nutritional impact of the program were not sufficient to assert whether change is needed. When considering whether limiting FMNV would reduce or improve the effectiveness of SNAP at alleviating hunger and malnutrition, there is very little information on which to base a policy change, particular one that singles out a low income group to restrict purchases. ^ Several states have attempted to restrict the purchase of FMNV but, to date, no such change has been implemented or tested. Conducting pilot studies on the restriction of FMNV, along with better data collection on SNAP purchases, would guide policy changes to the program. Although there are many potential public health benefits to restricting FMNV purchase using SNAP dollars, research is needed to quantify the cost impact of these benefits.^
