Abstract

This paper argues that exchange rate models rooted in the theory of Purchasing Power Parity (PPP) and balanced trade are fundamentally mis-specified, as evidenced by the disjuncture between: (1) the empirical evidence, which largely refutes PPP; and (2) the empirical result that ‘real’ productivity shocks are associated with observed secular trends in exchange rates. In the former case we have a theory without convincing evidence, and in the latter case we have empirical evidence in want of a consistent theory. If looked at from the perspective of a ‘cost of production’ theory of prices, such empirical results might not be so theoretically anomalous. So-called ‘real’ variables (especially productivity and unit labor costs), let in through the side door as ‘shocks’ to PPP equilibrium, may in fact be part and parcel of the formation of prices of production on an international scale through capitalist competition. The primary conclusion is that the empirical evidence supports a cost of production theory of the terms of trade and the real exchange rate. The empirical evidence in support of the Balassa–Samuelson model of the exchange rate is re-interpreted in this light. In this interpretation, parity holds only in terms of rates of return on investment which, in the classical tradition, are presumed to equalize across industries internationally.     

A discrete choice experiment to assess patients’ preferences for HIV treatment in the urban population in Colombia

Abstract

Aim: This study aimed to assess patients’ preferences for HIV treatment in an urban Colombian population.

Methods: A Discrete Choice Experiment (DCE) was conducted. Urban Colombian HIV patients were asked to repetitively choose between two hypothetical treatments that differ in regard to five attributes ‘effect on life expectancy’, ‘effect on physical activity’, ‘risk of moderate side effects, ‘accessibility to clinic’ and ‘economic cost to access controls’. Twelve choice sets were made using an efficient design. A Mixed Logit Panel Model was used for the analysis and subgroup analyses were performed according to age, gender, education level and sexual preference.

Results: A total of 224 HIV patients were included. All attributes were significant, indicating that there were differences between at least two levels of each attribute. Patients preferred to be able to perform all physical activity without difficulty, to have large positive effects on life expectancy, to travel less than 2?h, to have lower risk of side-effects and to have subsidized travel costs. The attributes ‘effect on physical activity’ and ‘effects on life expectancy’ were deemed the most important. Sub-analyses showed that higher educated patients placed more importance on the large positive effects of HIV treatment, and a more negative preference for subsidized travel cost (5% level).

Limitations: A potential limitation is selection bias as it is difficult to make a systematic urban/rural division of respondents. Additional, questionnaires were partly administered in the waiting rooms, which potentially led to some noise in the data.

Conclusions: Findings suggests that short-term efficacy (i.e. effect on physical activity) and long-term efficacy (i.e. effect on life expectancy) are the most important treatment characteristics for HIV urban patients in Colombia. Preference data could provide relevant information for clinical and policy decision-making to optimize HIV care.     

Limited asset market participation and the consumption‐real exchange rate anomaly

Abstract Under efficient consumption risk sharing, as assumed in standard international business cycle models, a country's aggregate consumption rises relative to foreign consumption, when the country's real exchange rate depreciates. Yet empirically, relative consumption and the real exchange rate are essentially uncorrelated. This paper shows that this ‘consumption‐real exchange rate anomaly’ can be explained by a simple model in which a subset of households trade in complete financial markets, while the remaining households lead hand‐to‐mouth (HTM) lives. HTM behaviour also generates greater volatility of the real exchange rate and of net exports, which likewise brings the model closer to the data.     

A re-examination of the impacts of macroeconomic and financial shocks on real exchange rate fluctuation: evidence from G7 and Asian countries

ABSTRACT

This paper aims to investigate the sources of real exchange rate fluctuation by utilizing sign restrictions in structural vector autoregressive (SVAR) method. Under an agnostic identification scheme, the empirical results show that the delayed overshooting puzzle still exists in response to monetary shock even if price puzzle is ruled out by construction. In contrast, all countries experience a significant initial real depreciation, and then gradually appreciate in response to currency risk premium (CRP) shock. This finding is consistent with Dornbusch’s overshooting model. In addition, I examine the importance of investors’ expectations in determining the short-term variations in the real exchange rate. The results indicate that the CRP and expectation shocks obviously outperformed the demand, supply and monetary shocks in terms of explaining the real exchange rate fluctuation.     

Personhood and Human Richness: Good and Well-Being in the Capability Approach and Beyond

This paper aims at developing the Capability Approach's (CA) underlying philosophical anthropology and ethics by focusing on the work of its major exponents, Amartya Sen and Martha Nussbaum. I first discuss CA's critique of happiness as subjective well-being and defend the idea of ‘flourishing’ which ultimately refers to the Aristotelian concept of eudaimonia. I then focus on the notions of ‘good’ and ‘well-being’ and address the problem of the compatibility between a substantive notion of the Good (expressed through universal moral values) and individual preferences. I thus tackle the issue of adaptive preferences (which is investigated both from a methodological and an ethical perspective) and suggest that the process of adaptation should be thought in the dynamic frame of the constitution of the self. Therefore, in the second half of the paper I investigate the CA's idea of personhood and focus on some important assumptions behind its underlying anthropological model – above all the notion of ‘human richness’. As a result, I first point out the dynamic dimension of personhood, according to which individuals are ‘becoming themselves’ in search of self-realisation and construction of their identities. Second, I highlight its relational dimension, according to which every one is the expression of the anthropological richness and at the same time represents the highest possibility of richness for every other one.     

The instability principle revisited: an essay in Harrodian dynamics

Abstract

Harrod's contribution to economic dynamics is very often reduced to the dynamic equation whose character is unstable. Growth theory and cycle theory based on Harrod's contributions aimed at reducing this instability. Following Harrod, who was strongly opposed to the ‘knife-edge’ interpretation, we define the warranted rate of growth as a ‘moving equilibrium’ and focus on its interaction with the effective rate of growth. Our simple Harrodian model generates various dynamics from stable path, to growth cycle and corridor of stability.     

Estimating a monetary policy reaction function for the dominican republic

Abstract

The paper specifies and estimates a hybrid McCallum–Taylor monetary policy reaction function for the Dominican Republic (DR). The estimated reactions suggest that the Central Bank of the DR has been biased towards targeting the exchange rate. These findings are in line with the evidence on the fear-of-floating characteristic of developing countries. An evaluation of the estimated rule's historical performance shows that monetary base growth below (above) that implied by the ‘average’ policy reaction is associated with better (worse) macroeconomic performance.     

An evening at the theatre: using choice experiments to model preferences for theatres and theatrical productions

This article examines people's preferences and demand for live theatre. It investigates the preferences for people attending a regional theatre, Northern Stage in Newcastle, in relation to other live theatres they could attend, and in relation to the attributes of theatrical productions and ticket price. It uses a Stated Preference (SP), discrete choice experiment, to assess people's utility and Willingness To Pay (WTP) for the different attributes of theatrical productions. The model assesses the effect of the attributes of plays on choice; and the impact of Socio-Economic (SE) and demographic variables on choice and demand. Results reveal the heterogeneity of theatregoers’ tastes for different types of plays and ticket prices. The models reveal the significance of ‘reviews’ and ‘Word Of Mouth’ (WOM) opinions on plays, as the most important variables determining choice.     

Enrico Barone's ‘Ministry of Production’: Content and Context

Abstract

Enrico Barone's famous article on economic planning, ‘Il Ministro della Produzione nello Stato Collettivista’ (‘The Ministry of Production in the Collectivist State’), which showed the theoretical possibility of an economically efficient collectivist planned economy, was published in Giornale degli Economisti in 1908. Barone's article has been widely cited, particularly in the comparative economic systems literature, but it has not been very widely read or analysed in recent years, and there is not much literature that places Barone's ‘Ministry’ model in the context of his other works or in its historical, social, or ideological context. The aims of this article are: (a) to analyse and clarify Barone's model in depth; (b) to place it in the context of Barone's other writings and the literature on the subject; and (c) to examine the apparent contradiction between Barone's hostility to socialism and his attempt to formulate the pure theory of the collectivist economy.     

CONSUMPTION EXTERNALITIES, PREFERENCE CHANGES AND THE 'SAMARITAN'S DILEMMA'

This paper examines the desirability of an exogenously induced change in the preferences of individuals in an economy characterized by (i) asymmetrical, localized positive consumption externalities, (ii) private, non-market, negotiation-free transfers, and (iii) the ‘Samaritan's dilemma.’ A model is analysed in which a benefactor (individual 1) makes an unrestricted voluntary transfer to a beneficiary (individual 2) who ran use the transfer to increase 2's consumption of either a purely private good x or a good y that generates external benefits for 1. Once 1 makes a transfer to 2, 1 cannot control how 2 spends it. If 2 fails to take into account this externality, then good y is under consumed and a loss in social welfare results. When such externalities and their concomitant welfare losses arise, conventional solutions are frequently inappropriate, impractical or impossible. This power shows that exogenously inducing the adoption of new externality internalizing preferences by the benefactor and the beneficiary not only increases the benefactor's transfer and the beneficiary's consumption of good y but also produces a ‘socially superior’ state. The welfare improvement is measured in terms of a welfare criterion that is based on the initial and new preferences of each individual     

Has the ‘franc fort’ exchange rate policy affected the inflationary dynamics? Theory and new evidence

Abstract

This paper examines the impact of the ‘franc fort’ policy implemented in France from 1983 on the inflationary dynamics by means of a square root Kalman filter approach. An interesting aspect of the analysis is the evidence that the ‘franc fort’ exchange rate policy had a significant impact on the inflationary dynamics in France through its credibility effects. These results confirm the imported credibility hypothesis according to which the French authorities accelerated the disinflation process by importing the German monetary policy credibility through the ‘hard peg’ of the franc–DM exchange rate. These findings show that inflation dynamics in France began to converge significantly to that in Germany after the implementation of the ‘franc fort’ policy, making more credible the plan for the final transition to the euro. Moreover, this analysis may also reveal much about the nature of potential success of the current initiative of the new member countries now in the process of joining the EU and looking eventually to adopt the euro.     

Exchange Rates,Expectations, and Monetary Policy: a NOEM Perspective*

We use a dynamic general‐equilibrium optimizing two‐country model to analyze how the formation of exchange rate expectations shapes the effects of a monetary policy shock in an open economy. We also provide empirical evidence on how traders in foreign exchange markets form exchange rate expectations. Our model implies that the short‐run output effect of a permanent monetary policy shock diminishes if “technical traders” form the type of regressive exchange rate expectations we find in our empirical analysis. If the influence of technical traders is strong enough, a permanent expansionary monetary policy shock can result in a temporary decline of the output in the country in which it takes place. The output effect of a temporary monetary policy shock is magnified when technical traders form regressive exchange rate expectations.     

Profit-sharing versus interest-taking in the Kaldor–Pasinetti theory of income and profit distribution

Abstract

This paper reformulates the Kaldor–Pasinetti model of income and profit distribution by introducing the interest rate from the very outset of the model but maintaining other Kaldor–Pasinetti assumptions intact. It is shown that the profit rate and the share of profits in national income are not independent from either the capitalists' or workers' propensity to save. Many contributors to the theory of income and profit distribution have erred in attributing a potentially positive impact of the interest rate upon profits. The interest rate is always and everywhere a tax on functional and personal incomes together. This result explains Schumpeter's observation that ‘Interest acts as a tax upon profit.’ In an alternative model, workers receive a share of profits instead of fixed contractual interest. It is shown that the profit rate and share are not independent from either propensity to save. Furthermore, the workers' share of profits has a positive impact on the rate and share of profits. This implies that a profit sharing regime could be more conducive to capital accumulation and job creation. It is found that Pasinetti's Cambridge Equation is more akin to a profit sharing regime.     

Global equilibrium dynamics with stationary recursive preferences

We study the global dynamics of capital accumulation for a general two-sector model which is not necessarily convex and where preferences of an infinitely-lived agent are stationary but not additively separable. We obtain monotonicity and convergence results for capital under ‘normality’ assumptions on preferences and factor intensity assumptions on technology. We then derive results on oscillatory dynamics under alternative factor-intensity conditions or under the assumption of inferiority of ‘future utilities’. Finally, in an exchange model with two agents we show that utilities will be monotonic or oscillatory depending on the normality or inferiority of the preferences.     

Monetary policy and exchange rate dynamics in the Spanish economy

As the Spanish economy gets more integrated in international markets, the real exchange rate becomes a key determinant of the monetary transmission. In this paper we trace out the dynamic response of prices, output and the exchange rate following a monetary policy shock. We estimate a structural VAR model whose identification scheme is based on the long run properties common to a large class of models. The results suggest that a small model with efficient asset markets plus nominal inertia and long run monetary neutrality, captures the essential features of the monetary transmission mechanism in Spain. The interest rate shock is well identified and the exchange rate overshoots its long run value. There are no signs of liquidity puzzle nor of price puzzle or exchange rate puzzle either.     

The specificity of manufacturing in Marx's economic thought

Abstract

This article examines Marx's approach to manufacturing and the extent to which manufacturing could be considered to have a special place in Marx's economic thought, especially in relation to accumulation and growth. The important ‘progressive’ features of manufacturing that can be found in Marx's writings and which are discussed here include: division of labour; socialisation of labour; mechanisation; increasing returns to scale; learning-by-doing; technological advancement; and overall, superior potential for cumulative productivity increases. These insights anticipate some of the thinking around the specificity of manufacturing found in twentieth-century structuralist development economics and some heterodox schools of thought such as Kaldorian approaches. This article suggests an interpretation of Marx as having a two-dimensional conceptualisation of activity specificity, with not only sectoral but also ‘technological–organisational’ dimensions, where these two dimensions are not fully independent of each other.     

Bilateral monopoly: a contribution by Francesco Ferrara

Abstract

In this paper, we propose an interpretation of the application of ‘cost of reproduction’ of Francesco Ferrara to the exchange between two agents to highlight its relevance for the theory of bilateral monopoly. In the Teoria delle Mercedi, Ferrara gives a numerical example to explain price determination in the exchange between one buyer and one seller. Here, this example is translated into a mathematical model that reproduces the fundamental issues of the neoclassical debate on the indeterminacy of price in the Cournot model, and anticipates the solutions proposed by Edgeworth at the end of this debate.     

A Note on the Stability of Full Employment

This note investigates the stability properties of the Keynesian macro-model under the assumption of slow adjustment of nominal wages and expectations of inflation. First, the stability conditions of the 'flexible-interest-rate regime' are related to those derived by Cagan (1956) and Tobin (1975), emphasising the potentially destabilising effect of wage flexibility. Then, taking the restriction of a zero floor to the nominal interest rate into account it is shown that the model exhibits 'corridor stability'. From this follows the conjecture that increasing the rate of steady-state inflation makes it 'more probable' that the system returns to full-employment after a shock of given size.     

Verifying India’S Exchange Rate Regime in the Pre-Reforms Period (1975–91)

Verifiability of an announced exchange rate regime becomes important in the context of credibility and transparency of a regime. These latter ideas become especially significant in the context of the currently reigning hypothesis of the missing middle, which postulates that exchange rate regimes intermediate to the corner regimes of ‘free floating’ and ‘firm fixing’ are increasingly becoming nonviable in a world of greater international capital mobility as these intermediate regimes are more difficult to verify. This paper attempts to verify India’s exchange rate regime in the so-called basket arrangement period. Using auxiliary information about the regime, it estimates the confidential Indian basket and shows that the behaviour of India’s exchange rate was not exactly as per the announced regime.

     

Krishna Bharadwaj's “Return to Classical Theory”: an attempt towards an archaeological reconstruction

Abstract

In the wake of Sraffa's ‘return to classical theory’, Krishna Bharadwaj undertook a critical reassessment of Marshall's claim to continuity with classical theory in general and Ricardo's ‘intensive margin’ in particular. Her analysis is based on an analytical separation between two distinct ways of economic reasoning: the ‘surplus based’ and the ‘demand and supply based’ theories. Calling it an ‘archaeological reconstruction’ of the history of economic theories, I will examine how such an interpretation of theoretical shifts clarifies both the presuppositions behind analysing at the ‘margin’, and hence its radical departure from the conceptual content of the classical theory.
