A new geography of preferences for Sub-Saharan African countries in a globalizing trading system

Trade between developing countries, or South-South trade, has been growing rapidly in recent years following significant reductions in tariffs. However, significant barriers remain, and there is currently reluctance among many developing countries to undertake further reductions. In addition African countries and in particular least developed African countries are still marginal players in this reframing of geography of trade. The erosion of preferential access to Northern markets remains their major concern and the status quo in multilateral liberalization could be seen as a desirable scenario. This emphasis on developed countries markets, principally Europe and the US, is likely to represent a missed opportunity for African countries. Unless those countries are granted broader preferences by the European Union and other developed countries, especially in agriculture, significant gains would be obtained from trade preferences provided by other developing countries. To assess this we compare the potential effects of the removal of barriers on trade between African countries and other developing countries with the gains from developed country liberalization. A general equilibrium model containing information on preferential bilateral tariffs is used to estimate the impacts

Tracking the Italian employees'TFR over their working life careers

In this paper we evaluate the expected evolution of the Trattamento di ?ne rapporto over the Italian employees?working life careers. We use adiminstrative (INPS) data to disentangle the amount that is expected to be accumulated until retirement, the amount expected not to accrue because of discountinuos working careers and/or paid as an anticipated withdrawal. This is relevant in the light of the recent pension system reforms that encourage the diversion of the TFR to pension funds.

Trade Liberalisation and Informality: New stylized facts

The relationship between trade liberalisation and informal activity has not received the attention, whether theoretical or empirical, that it may deserve. The conventional view poses that trade liberalisation would cause a rise in informality. This paper uses three different data sets to assess the sign of the relationship. Empirical results provide a mixed picture. Macro founded data tend to produce results supporting the conventional view. Micro founded data do not. Empirical results also suggest that while informal output increases with deeper trade liberalisation, informal employment falls.Informal Sector, Trade Liberalisation, Cross-sectional Analysis, Time Series Analysis, Panel Analysis

Exchange Rate Appreciations, Labor Market Rigidities, and Informality

This paper works at the interface of the literature exploring the raison d’etre of the informal labor market and that explaining the real exchange rate appreciations occurring in many Latin American countries during periods of reform. We first build a small country-Australian style model where the informal sector is seen as an unregulated non-tradables sector, augmented by heterogeneity in entrepreneurial ability and capital adjustment costs. We then examine the behavior of the model with and without a formal sector rigidity. We show that the co-movements of relative formal/informal incomes, formal/informal sector size, and the real exchange rate can offer insight into the level of distortion in the labor market and the source of ER fluctuations. We then explore time series data from Brazil, Colombia and Mexico using multivariate co-integration techniques to establish what “regime” each country is in at various periods of time. Mexico, for instance, appears to be relative undistorted and the 1987-92 appreciation appears to be largely a function of a boom in the non-tradables sector rather than wage inertia. In spite of a secular expansion of the informal sector and there is little evidence of dualism or of a rigidity driven appreciation of the Real, from 1993-1996. Post 1995 Colombia corresponds to a classic segmented labor market and an appreciation partly driven by labor market rigidities. Graphical analysis suggests that neither the Argentine appreciation (1988-1992) or the celebrated Chilean appreciation (1975-1982) were driven by inertial forces.

1/N and Long Run Optimal Portfolios: Results for Mixed Asset Menus

Recent research [e.g., DeMiguel, Garlappi and Uppal, (2009a), Rev. Fin. Studies] has cast doubts on the out-of-sample performance of optimizing portfolio strategies relative to a naive, equally-weighted ones. However, most of the existing results concern the simple case in which an investor has a one-month horizon and mean-variance preferences. In this paper, we examine whether this finding holds for longer investment horizons, when the asset menu includes bonds and real estate beyond stocks and cash, and when the investor is characterized by constant relative risk aversion preferences which are not locally mean-variance for long horizons. Our experiments indicates that power utility investors with horizons of one year and longer would have on average benefited, ex-post, from an optimizing strategy that exploits simple linear predictability in asset returns over the period January 1995 - December 2007. This result is insensitive to the degree of risk aversion, to the number of predictors being included in the forecasting model, and to the deduction of transaction costs from measured portfolio performance.equally weighted portfolios; long investment horizon; real-time strategic asset allocation; public real estate vehicles; ex post performance; predictability; parameter uncertainty

International diversification and industry-related labor income risk

Do equity markets help diversifying away industry-related labor income risk? This paper reconsiders the hedging role of stock markets by focusing on international equity diversification, rather than domestic asset allocation, and on industry wage, rather than individual labor income. We test for differences in implied equilibrium equity portfolios across investors belonging to different industry-country pairs. We compare these industry-based portfolio holdings to the one that is optimal for an investor endowed with the average home-country labor income. Our results resurrect the role of equities in hedging wage risk by uncovering remarkable heterogeneity across industries within each investing country. Our analysis also delivers insights concerning the role of occupational pension funds in designing optimal portfolios for their members.optimal portfolio choice; international diversification; labor income risk; industry-specific human capital; occupational pension funds

Toward Semantics-aware Representation of Digital Business Processes

An extended enterprise (EE) can be described by a set of models each representing a specific aspect of the EE. Aspects can for example be the process flow or the value description. However, different models are done by different people, which may use different terminology, which prevents relating the models. Therefore, we propose a framework consisting of process flow and value aspects and in addition a static domain model with structural and relational components. Further, we outline the usage of the static domain model to enable relating the different aspects

Investing for the long-run in European real estate

We calculate optimal portfolio choices for a long-horizon, risk-averse investor who diversifies among European stocks, bonds, real estate, and cash, when excess asset returns are predictable. Simulations are performed for scenarios involving different risk aversion levels, horizons, and statistical models capturing predictability in risk premia. Importantly, under one of the scenarios, the investor takes into account the parameter uncertainty implied by the use of estimated coefficients to characterize predictability. We find that real estate ought to play a significant role in optimal portfolio choices, with weights between 12 and 44 percent. Under plausible assumptions, the welfare costs of either ignoring predictability or restricting portfolio choices to traditional financial assets only are found to be in the order of 150-300 basis points per year. These results are robust to changes in the benchmarks and in the statistical framework.Real estate investment ; Rate of return ; European Union
