Deadlines and software: disentangling local government accounting reforms in Brazil

ABSTRACT

This paper shows how ongoing accounting reforms in Brazilian local governments were affected by a shift from a universal to a gradual implementation approach. Deadlines being postponed led to a decrease in local governments’ willingness to reform. This effect varied according whether the accountants involved depended on commercial software to operate a particular accounting policy. An important finding from this research was that software providers are to some extent setting the IPSAS implementation agenda in Brazil.     

Financialization and Portuguese real investment: A supportive or disruptive relationship?

The article makes an empirical analysis of the relationship between financialization and real investment by Portuguese nonfinancial corporations from 1979 to 2013. In theory, while financialization leads to a rise in financial investments by nonfinancial corporations and thus deviates funds from real investment, it also intensifies the pressure for financial payments and therefore restricts the funds available for real investment. We estimate an aggregate investment function including control variables (profitability, debt, cost of capital and output growth) and two measures of financialization (financial receipts and financial payments). The study concludes that there is a long-term investment equation, and finds evidence that the process of financialization has hampered real investment largely as a result of financial payments. The article also finds that profitability and debt are both detrimental to real investment.     

论西方的崛起:肯尼斯·彭慕兰的大分流研究

为什么在世界文明大国中,只有欧洲在19世纪取得了具有革命意义的转变.肯尼斯·彭慕兰的《大分流》对此做出了解释.他认为,至迟到1800年,中国的生活水准和生产水平与欧洲大致相当.英格兰之所以首先工业化是因为充足的煤炭和新大陆大量土地集约型资源的供应.本文认为彭慕兰的观点缺乏经验可信性.与潜在的和实际的欧洲内部贸易相比,由美洲进口为英格兰带来的"生态暴利"并不明显.而中国尽管在1500年后在中亚和西南亚获得了新的领土,带来了巨大的"生态暴利",但并没有获得任何工业突破.     

Pair-copulas modeling in finance

This paper concerns itself with applications of pair-copulas in finance, and bridges the gap between theory and application. We provide a broad view of the problem of modeling multivariate financial log-returns using pair-copulas, gathering together for this purpose theoretical and computational results from the literature on canonical vines. From the practitioner’s viewpoint, the paper shows the advantages of modeling through pair-copulas and makes clear that it is possible to implement this methodology on a daily basis. All the necessary steps (model selection, estimation, validation, simulations, and applications) are discussed at a level easily understood by all data analysts.     

Modelling Foreign Real Estate Investment: The Spanish Case

Foreign real estate investment in Spain has grown considerably during the last decade, representing around 40% of total foreign direct investment inflows. This trend has exerted an important macroeconomic effect maintaining a long lasting housing bubble and contributing significantly to finance the rising current account deficit. Foreign real estate investment in Spain is mostly of a housing acquisition type and therefore the analysis of its determinants requires a specific approach. In this sense, neither a pure foreign direct investment nor a portfolio theoretical model might be useful. So we propose a modelling of foreign real estate investment for Spain from the point of view of a demand for tourism services and from a financial focus. Using time series data from 1990 to 2007 the hypothesis arising from our foreign real estate investment modelling reveals the consistency of this approach. There seem to be relevant determinants from the demand side and from the financial dimension. Indeed, Gross Domestic Product per capita, expected capital gains, travel costs, tourism agglomeration and housing prices are all relevant factors explaining Foreign real estate investment. We consider that this case study may also be applied to other countries sharing similar foreign real estate investment type flows.     

An Extension of the Structural Change Model to International Economic Relations

In this paper Pasinetti's model of structural economic dynamics (1981) is extended to consider international economic relations. Conditions for full employment, full expenditure of income and equilibrium of the trade balance are established for an open economy that requires capital goods to produce final commodities. Analytical results concerning the benefits from free trade and international learning are formally studied. In addition, static and dynamic aspects of the ‘principle of comparative cost advantage’ are analysed considering the determinants of the specialization level.     

Optimal portfolio choices using financial leverage

This paper investigates the role of leverage in determining the investor's optimal asset allocation over multiperiod investment horizons. To do this, we allow investors to lever their financial position by borrowing from credit markets. GMM methods are used to estimate and test the optimal portfolio weights and individual's optimal choice of financial leverage. These optimal choices are assumed to be parametric functions of a set of state variables describing the evolution of the economy. The empirical application of this methodology to a portfolio of cash, bonds and stocks reveals that a) financial leverage limits the reaction of investors to changes in the investment opportunity set; b) individuals increase leverage during recessions and deleverage in expansionary periods; c) optimal portfolio weights and financial leverage are negatively related to the degree of investor's risk aversion and positively related to the investment horizon.     

A two‐sector neo‐Kaleckian model of growth and distribution: Investment allocation and evolutionary dynamics

This paper focuses on the two‐sector neo‐Kaleckian model of growth and distribution that was developed by Dutt (1990) and challenged by Park (1995). We develop a variant of this model, focusing on the supply‐side to solve the overdetermination problem that was raised by Park. Finally, we introduce evolutionary dynamics to model the investment flows between the capital and consumer goods sectors. In this setup, the sectoral profit rates and the size of capital stocks wield an essential role upon the entrepreneur’s decision on which sector to invest in. This model is perfectly determined and it generates a stable evolutionary equilibrium over the long term.     

Coffee exports and industrialization in Brazil

We investigate the dynamic relationship between coffee exports and machinery imports in Brazil from 1869 to 1939. Our tests reveal cointegration and bidirectional causality in the temporal sense. This evidence suggests that foreign exchange real revenues from coffee exports were important for the onset of industrialization, as machinery imports proxy for real investment demand. Capital growth, in turn, also helped to boost the country’s exports.
