Trade liberalization,democratization, and technology adoption

A general equilibrium theory with heterogeneous skills predicts a complementarity between trade and democracy in creating demand for superior technologies. Trade liberalization or democratization alone may lead to vested interests that limit technology adoption. We use panel data on technology adoption, at a disaggregated level, for the period 1980–2000. Exploiting within-country variation over time and the heterogeneous timing of trade liberalization and democratization, we document a significant and sizable positive interaction between trade openness and democratization for technology adoption. The result that transitions to open democracies are beneficial for technological dynamics is robust to a large set of checks.     

Gender Differences in Financial Education: Evidence from Primary School

Today, financial and economic education is a primary issue in academia and among policy makers, and there is great interest towards programmes that are able to boost it. In this paper, we test whether a programme (“treatment”) of financial education on savings, targeted to children aged 8 and 9 is effective and to what extent. We measure the interest rate required by the children before and after the treatment to accept postponing a reward, computing its variation and comparing this with that of a control group. We find evidence that the overall initiative is helpful in decreasing the level of impatience of children and the number of inconsistent choices of boys. Our findings invite to reflect on the gender neutrality of programmes of financial education.     

Complexity and financial stability in a large random economy

I study the limit of a large random economy, in the ideal case of perfect competition, where full information is available to all market participants, and where a set of consumers invests in financial instruments engineered by banks in order to optimize their future consumption. This provides a picture of how unregulated financial innovation pushes an economy towards the ideal limit of complete markets. Hedging new products with existing products allows financial institutions to reduce the associated risk and hence the risk premium. This has the expected consequence that markets, under such ideal conditions, converge to market completeness as the repertoire of financial instruments expands. As markets approach completeness, however, two ‘unintended consequences’ also arise: (i) equilibrium portfolios develop a marked susceptibility to idiosyncratic shocks and/or parameter uncertainty and (ii) hedging engenders divergent trading volumes in the interbank market. Combining these suggests an inverse relation between financial stability and the size of the financial sector, which can be quantified within the present framework. These results suggest that even under perfect competition and symmetric information, the pursuit of market efficiency—in terms of completeness—may erode financial stability. The proliferation of financial instruments exacerbates the effects of market imperfections and, in order to prevent an escalation of perverse effects, markets may require institutional structures that become more and more substantial as their complexity expands.     

The Target Zone Model, Non-Linearity and Mean Reversion: is the Honeymoon Really Over?

We estimate a target zone model for three ERM exchange rates for 1983–6 and 1987–91 by the method of simulated moments, taking account of the continuous time specification by using daily data with the interruptions of holidays and weekends. Specification tests are unable to reject the model. The estimates imply, however, an essentially linear relationship between the exchange rate and the fundamentals, with a very limited 'honeymoon effect'. Using Monte Carlo simulations, calibrated on the estimates, we find that standard tests for mean reversion of the exchange rate would largely reject the target zone model when, in fact, it held.     

Modelling the impact of alternative pricing policies on an urban multimodal traffic corridor

This paper investigates the effects of alternative or joint schemes of road pricing and parking pricing to verify if private behaviour in operating parking facilities, road tolling and transit systems can lead to profitable results in the private sector and for public welfare. The evaluation is carried out using an idealised urban multimodal traffic corridor with some numerical examples that show the effects of different pricing policies. A Deterministic User Equilibrium assignment procedure is used to calculate certain performance indicators such as user travel costs, social costs and private profit. The results show that the system is highly sensitive to pricing policy and that a proper joint pricing of park-and-ride facilities, city centre parking and road tolls can be developed to simultaneously attain good private and social benefits.     

Post-Keynesian endogenous money theory: Horizontalists,structuralists and the paradox of illiquidity

The paper aims to provide a theoretical advancement in the post-Keynesian debate between horizontalists and structuralists by offering an additional theoretical support to the horizontalist view. Through the newly introduced notion of paradox of illiquidity, a critique to the endogenous money–liquidity preference model is developed, by focusing on the relationship between the volume of loans and the mark-up. The paradox of illiquidity aims to deny: (a) the idea of a banking sector achieving illiquid position during its lending activities and, consequently, (b) the view of an upward sloping credit supply curve.
