Enforcement problems and secondary markets

There is a large and growing literature that studies the effects of weak enforcement institutions on economic performance. This literature has focused almost exclusively on primary markets, in which assets are issued and traded to improve the allocation of investment and consumption. The general conclusion is that weak enforcement institutions impair the workings of these markets, giving rise to various inefficiencies.But weak enforcement institutions also create incentives to develop secondary markets, in which the assets issued in primary markets are retraded. This paper shows that trading in secondary markets counteracts the effects of weak enforcement institutions and, in the absence of further frictions, restores efficiency.

The changing relationship between tax and financial reporting in Spain

The degree of connection between tax and financial reporting is regarded as a key factor in the study of international accounting differences. The position for Spain is briefly outlined in previous research but without examination of any specific accounting issues except, in outline only, depreciation and the tax-free revaluation of assets from 1977 to 1983. The absence of a detailed study of the major tax/accounting linkages for Spain is of particular importance because the relationship is regarded as having changed dramatically in the early 1990s, from a position of tax dominance. In order to measure the links between tax and financial reporting, we adopt the methodology of Lamb et al. (1998) by assessing major accounting topics using a five-case classification shown as Table 1. We refute the proposition that suggests that the link between tax/accounting has been reduced substantially.

Value and depreciation of mineral resources over the very long run: An empirical contrast of different methods

The paper contrasts empirically the results of alternative methods for estimating thevalue and the depreciation of mineral resources. The historical data of Mexico andVenezuela, covering the period 1920s-1980s, is used to contrast the results of severalmethods. These are the present value, the net price method, the user cost method andthe imputed income method. The paper establishes that the net price and the user costare not competing methods as such, but alternative adjustments to different scenariosof closed and open economies. The results prove that the biases of the methods, ascommonly described in the theoretical literature, only hold under the most restrictedscenario of constant rents over time. It is argued that the difference between what isexpected to happen and what actually did happen is for the most part due to a missingvariable, namely technological change. This is an important caveat to therecommendations made based on these models.

Reporting intellectual capital in Spain

This study reports on the analysis of annual reports from 14- listed companies in Spainover a five-year period, from 1998 to 2002. Companies in the sample are selected on thebasis of their knowledge-based assets and incentives to report on Intellectual Capital.The empirical analysis is twofold:1) Firstly, we analyse the value of intellectual capital using a value-based approach,through the difference between market and book value over the period considered. Results show that there is a general decrease in the 'hidden value' of these companies, probably due to the general trend in stock markets.2) Secondly, we carry out a content-based analysis of the complete annual reports of the companies over the five year period. Preliminary findings seem to suggest that although the level of disclosure has increased over time, this is mainly in the form of narrative. Overall, the level of disclosure of intellectual capital remains low.

Valuation bubbles and sequential bubbles

Price bubbles in an Arrow-Debreu valuation equilibrium in infinite-timeeconomy are a manifestation of lack of countable additivity of valuationof assets. In contrast, known examples of price bubbles in sequentialequilibrium in infinite time cannot be attributed to the lack of countableadditivity of valuation. In this paper we develop a theory of valuation ofassets in sequential markets (with no uncertainty) and study the nature ofprice bubbles in light of this theory. We consider an operator, calledpayoff pricing functional, that maps a sequence of payoffs to the minimumcost of an asset holding strategy that generates it. We show that thepayoff pricing functional is linear and countably additive on the set ofpositive payoffs if and only if there is no Ponzi scheme, and providedthat there is no restriction on long positions in the assets. In the knownexamples of equilibrium price bubbles in sequential markets valuation islinear and countably additive. The presence of a price bubble indicatesthat the asset's dividends can be purchased in sequential markers at acost lower than the asset's price. We also present examples of equilibriumprice bubbles in which valuation is nonlinear but not countably additive.

Desenvolvimentos estimados de custo amortizado e imparidade, segundo SNCRF - caso prático

O tema do Trabalho de Fim de Curso - “Desenvolvimentos Estimados de Custo Amortizado e Imparidade segundo SNCRF”, insere-se no âmbito da conclusão da Licenciatura em Contabilidade e Administração – Ramo Administração e Controlo Financeiro ministrada pelo ISCEE – Instituto Superior de Ciências Económicas e Empresariais. O trabalho ora apresentado, espelha uma análise sumária das normas internacionais e do novo normativo nacional no que diz respeito aos instrumentos financeiros com foco em tratamento contabilístico dado pelo método de custo amortizado e reconhecimento de perda por imparidade. Foi preparado com base em consulta de bibliografia especializada e normativos estabelecidos no país, pois permitirá ter acesso tanto a conteúdos teóricos como práticos o que implica um estudo mais abrangente de todos os recursos disponíveis. O desenvolvimento da temática foi orientado numa primeira etapa através de pesquisa necessária a construção do referencial teórico centrado por um lado na evolução teórica das normas internacionais sobre os instrumentos financeiros e consequentemente o tratamento dado pela nossa norma. Na segunda etapa, os casos práticos apresentam os principais casos de contabilização dos instrumentos financeiros utilizando o método de custo amortizado, e reconhecimento de imparidade de acordo com o SNCRF, e a conclusão que se chegou é que o custo amortizado implica a utilização do método de taxa de juro efectiva menos qualquer perda por imparidade, sendo que o método de taxa de juro efectiva distribui os pagamentos e recebimentos dos juros ao longo do período do instrumento financeiro aplicando a taxa de juro efectiva ao valor a transportar do activo ou de passivo de cada período, e uma entidade que usa o método de custo amortizado reconhece os activos financeiros e passivos financeiros pelo seu valor líquido no balanço, e à data de cada relato financeiro deve avaliar a imparidade de todos os activos financeiros e reconhecer perdas por imparidade, visto que, a imparidade representa uma redução no valor de um activo financeiro ou seja reflecte a depreciação (perda permanente) do valor de um activo financeiro e verifica quando a quantia recuperável for superior ao seu valor contabilístico.

Property enforcement as organized consent

This article develops and tests a theory of the institutions that makeproperty rights viable, ensuring their enforcement, mobilizing thecollateral value of assets and promoting growth. In contrast tocontractual rights, property rights are enforced in rem, being affectedonly with the consent of the right holder. This ensures enforcement butis costly when multiple, potentially colliding rights are held in thesame asset. Different institutions reduce the cost of gathering consentsto overcome this trade-off of enforcement benefits for consent costs:recording of deeds with title insurance, registration of rights and evena regimen of purely private transactions. All three provide functionallysimilar services, but their relative performance varies with the numberof transactions, the risk of political opportunism and regulatoryconsistency. The analysis also shows the rationality of allowingcompetition in the preparation and support of private contractswhile requiring territorial monopoly in recording and registrationactivities, this to ensure independence and protect third parties.

Optimal negligence rule under limited liability

We study the standard economic model of unilateral accidents, in its simplest form, assumingthat the injurers have limited assets.We identify a second-best optimal rule that selects as duecare the minimum of first-best care, and a level of care that takes into account the wealth ofthe injurer. We show that such a rule in fact maximizes the precautionary effort by a potentialinjurer. The idea is counterintuitive: Being softer on an injurer, in terms of the required level ofcare, actually improves the incentives to take care when he is potentially insolvent. We extendthe basic result to an entire population of potentially insolvent injurers, and find that the optimalgeneral standards of care do depend on wealth, and distribution of income. We also show theconditions for the result that higher income levels in a given society call for higher levels of carefor accidents.

Window-dressing in German interwar balance sheets

German accounting rules value assets and liabilities asymmetricallyand thus lead to grossly distorted balance sheets. In the interwardebate on a reform of disclosure regulation, financial expertsconsidered the (undisclosed) tax balance sheet, which had to bedrawn up separately for the corporate tax assessment, as a paradigmfor adequate financial disclosure. However, due to tax secrecy thaywere barred from analyzing tax documents. Using archival evidence,we analyze tax balance sheets from which the reliability of disclosedbalance sheets of the interwar period can be assessed. It emergesthat companies overstated their profits in the middand late 1920s,but grossly understated them in the Nazi economy.

Full insurance, asymmetric information and genetic testing

This paper extends previous resuls on optimal insurance trading in the presence of a stock market that allows continuous asset trading and substantial personal heterogeneity, and applies those results in a context of asymmetric informationwith references to the role of genetic testing in insurance markets.We find a novel and surprising result under symmetric information:agents may optimally prefer to purchase full insurance despitethe presence of unfairly priced insurance contracts, and other assets which are correlated with insurance.Asymmetric information has a Hirschleifer-type effect whichcan be solved by suspending insurance trading. Nevertheless,agents can attain their first best allocations, which suggeststhat the practice of restricting insurance not to be contingenton genetic tests can be efficient.

Specificity revisited: The role of cross-investments

Previous analysis has shown that traders may opt for specific technologies with nojoint productivity advantage as a way to commit themselves to trading jointly, butonly when long-term contracting is infeasible. This paper proves that speciÞcity canalso be optimal (by relaxing the budget-balance constraint) in settings with long-termcontracting. Traders will opt for specificity when one trader makes a cross-investmentand either (1) this cross-investment has a direct externality on the other trader, (2) bothparties invest, or (3) private information is present. The specificity (e.g. from non-salvageable investments, specific assets and technologies, narrow business strategies,and exclusivity restrictions) is equally effective regardless of which trader's alternativetrade payoff is reduced. Specificity supports long-term contracts in a broad rangeof settings - both with and without renegotiation. The theory also offers a novelperspective on franchising and vertical integration.

Measuring and explaining farm inefficiency in a panel data set of mixed farms

This paper aims to estimate a translog stochastic frontier production function in the analysis of a panel of 150 mixed Catalan farms in the period 1989-1993, in order to attempt to measure and explain variation in technical inefficiency scores with a one-stage approach. The model uses gross value added as the output aggregate measure. Total employment, fixed capital, current assets, specific costs and overhead costs are introduced into the model as inputs. Stochasticfrontier estimates are compared with those obtained using a linear programming method using a two-stage approach. The specification of the translog stochastic frontier model appears as an appropriate representation of the data, technical change was rejected and the technical inefficiency effects were statistically significant. The mean technical efficiency in the period analyzed was estimated to be 64.0%. Farm inefficiency levels were found significantly at 5%level and positively correlated with the number of economic size units.

Giffen goods and market making

This paper shows that information effects per se are not responsible forthe Giffen goods anomaly affecting competitive traders demands in multi-asset, noisy rational expectations equilibrium models. The role thatinformation plays in traders strategies also matters. In a market withrisk averse, uninformed traders, informed agents havea dual motive for trading: speculation and market making. Whilespeculation entails using prices to assess the effect of private signalerror terms, market making requires employing them to disentangle noisetraders effects in traders aggregate orders. In a correlated environment,this complicates a trader s signal-extraction problem and maygenerate upward-sloping demand curves. Assuming either (i) that competitive,risk neutral market makers price the assets, or that (ii) the risktolerance coefficient of uninformed traders grows without bound, removesthe market making component from informed traders demands, rendering themwell behaved in prices.

The dot-com bubble, the Bush deficits and the US current account

Over the past decade the US has experienced widening current account deficits and a steady deterioration of its net foreign asset position. During the second half of the 1990s, this deterioration was fueled by foreign investment in a booming US stock market. During the first half of the 2000s, this deterioration has been fuelled by foreign purchases of rapidly increasing US government debt. A somewhat surprising aspect of the current debate is thatstock market movements and fiscal policy choices have been largely treated as unrelated events. Stock market movements are usually interpreted as reflecting exogenous changes in perceived or real productivity, while budget deficits are usually understood as a mainly political decision. We challenge this view here and develop two alternative interpretations. Both are based on the notion that a bubble (the dot-com bubble) has been driving the stock market, but differ in their assumptions about the interactions between this bubble and fiscal policy (the Bush deficits). The benevolent view holds that a change in investorsentiment led to the collapse of the dot-com bubble and the Bush deficits were a welfare-improving policy response to this event. The cynical view holds instead that the Bush deficits led to the collapse of the dot-com bubble as the new administration tried to appropriate rents from foreign investors. We discuss the implications of each of these views for the future evolution of the US economy and, in particular, its net foreign asset position.

A influência do e-learning no capital humano

Na Europa e nas últimas décadas do Século XX, a emergência da Sociedade de Informação veio impor às organizações a necessidade de que, para além das inovações tecnológicas, haja uma preocupação relativamente aos bens intangíveis como a informação, as novas metodologias de trabalho e o know how (Batista, 2002). Paralelamente a estas inovações, as Instituições de Ensino Superior têm contribuído para a evolução do Capital Humano, como ativo intangível intrínseco ao Homem. Em Portugal e no contexto do Ensino/Formação a Distância parecem continuar a existir, ainda, em algumas instituições, problemas de identificação, e de descriminação das vantagens no que concerne à estrutura aberta e flexível, com o estudante/formando a ter algumas dificuldades em adaptar o seu perfil e interesses profissionais ao tipo de aprendizagem que mais se lhe adequa. O e-learning surge como um método de Ensino/Formação a Distância, só possível com a especificidade dos processos pedagógicos e em complementaridade com as Tecnologias de Informação e Comunicação (TIC), uma vez que são estas que lhe dão o suporte necessário à sua concretização. O e-learning ao proporcionar novas formas de comunicação, de interação e de confronto de ideias, permite uma aprendizagem baseada na partilha de saberes, tendo em consideração as experiências e os objetivos profissionais dos formandos. Dentro destes pressupostos, achámos importante fazer uma investigação a partir de Instituições de Ensino Superior Portuguesas, de modo a percebermos qual o papel e a influência que o e-learning desempenha nos objetivos das organizações académicas em geral e no Capital Humano dos seus Estudantes/Formandos em particular. A partir da questão da investigação foram definidos os objetivos e hipóteses de investigação de modo a que ao ser enunciada uma metodologia esta englobe fatores que foquem os elementos necessários à confirmação, ou não, dos pressupostos enunciados. Foi analisada documentação diversa, criado um questionário e conduzidas entrevistas, de modo a obter e potenciar a informação necessária e suficiente para o efeito. A recolha de dados para posterior análise e os resultados depois de interpretados, permitirão responder aos propósitos expressos desde o início da investigação.
