Although it might have been expected that, by this point in time, the unacceptability of the marginal productivity theory of the return on capital would be universally agreed, that is evidently not the case. Popular textbooks still propound the dogma to the innocent. This note is presented in the hope that a succinct indication of the origins of the theory it will contribute to a more general appreciation of the unrealistic and illogical nature of this doctrine.

Employing an endogenous growth model with human capital, this paper explores how productivity shocks in the goods and human capital producing sectors contribute to explaining aggregate fluctuations in output, consumption, investment and hours. Given the importance of accounting for both the dynamics and the trends in the data not captured by the theoretical growth model, we introduce a vector error correction model (VECM) of the measurement errors and estimate the model’s posterior density function using Bayesian methods. To contextualize our findings with those in the literature, we also assess whether the endogenous growth model or the standard real business cycle model better explains the observed variation in these aggregates. In addressing these issues we contribute to both the methods of analysis and the ongoing debate regarding the effects of innovations to productivity on macroeconomic activity.

An extensive economics and regional science literature has discussed the importance of social capital for economic growth and development. Yet, what social capital is and how it is formed are elusive issues, which require further investigation. Here, we refer to social capital in terms of civic capital and good culture , as rephrased by Guiso, Sapienza and Zingales (2010) and Tabellini (2010). The accumulation of this kind of capital allows the emerging of regional informal institutions, which may help explaining diff erences in regional development. In this paper, we take a regional perspective and use exploratory space and space-time methods to assess whether geography, via proximity, contributes to the formation of social capital across European regions. In particular, we ask whether generalized trust, a fundamental constituent of social capital and an ingredient of economic development, tends to be clustered across space and over time. From the policy standpoint, the spatial hysteresis of regional trust may contribute to the formation of spatial traps of social capital and act as a further barrier to regional economic development and convergence.

The purpose of this note is to supplement the author’s earlier remarks on the unsatisfactory nature of the neoclassical account of how the return on capital is determined. (See Strathclyde Discussion Paper 12-03: “The Marginal Productivity Theory of the Price of Capital: An Historical Perspective on the Origins of the Codswallop”). The point is made via a simple illustration that certain matters which are problematical in neoclassical terms are perfectly straightforward when viewed from a classical perspective. Basically, the marginalist model of the nature of an economic system is not fit for purpose in that it fails to comprehend the essential features of a surplus-producing economic system as distinct from one merely of exchange.

This paper develops a dynamic general equilibrium model to highlight the role of human capital accumulation of agents differentiated by skill type in the joint determination of social mobility and the skill premium. We first show that our model captures the empirical co-movement of the skill premium, the relative supply of skilled to unskilled workers and aggregate output in the U.S. data from 1970-2000. We next show that endogenous social mobility and human capital accumulation are key channels through which the effects of capital tax cuts and increases in public spending on both pre- and post-college education are transmitted. In particular, social mobility creates additional incentives for the agents which enhance the beneficial effects of policy reforms. Moreover, the dynamics of human capital accumulation imply that, post reform, the skill premium is higher in the short- to medium-run than in the long-run.

This paper undertakes a normative investigation of the quantitative properties of optimal tax smoothing in a business cycle model with state contingent debt, capital-skill complementarity, endogenous skill formation and stochastic shocks to public consumption as well as total factor and capital equipment productivity. Our main finding is that an empirically relevant restriction which does not allow the relative supply of skilled labour to adjust in response to aggregate shocks, signi cantly changes the cyclical properties of optimal labour taxes. Under a restricted relative skill supply, the government fi nds it optimal to adjust labour income tax rates so that the average net returns to skilled and unskilled labour hours exhibit the same dynamic behaviour as under fl exible skill supply.

Micro-econometric evidence reveals high private returns to education, most prominently in low-income countries. However, it is disputed to what extent this translates into a macro-economic impact. This paper projects the increase in human capital from higher education in Malawi and uses a dynamic applied general equilibrium model to estimate the resulting macroeconomics impact. This is contingent upon endogenous adjustments, in particular how labour productivity affects competitiveness and if this in turn stimulates exports. Choice among commonly applied labour market assumptions and trade elasticities results in widely different outcomes. Appraisal of such policies should consider not only the impact on human capital stocks, but also adjustments outside the labour market.

J S Mill’s enigmatic "Fourth Proposition on Capital" has been brought to our notice by Steven Kates (2015). Kates takes a positive view of the proposition. Our focus is not, however, on Kates, but on the aforesaid proposition. The purpose of this paper is to demonstrate, via close examination of Mill’s explanatory examples, just how unsatisfactory are its foundations. We conclude that the doubters are justified: Mill’s Fourth Proposition is, demonstrably, a muddle.

Este estudo plantexa as interaccións habidas entre pensamento económico e a toma de decisións políticas a traveso dun caso concreto. Analizámo-las propostas referidas á política agraria plantexadas polo Ministro de Fomento Eugenio Montero Ríos (1885-1886) e a influencia que nelas exerciu o economista Joaquín Díaz de Rábago. Ámbolos dous foron galegos destacados da segunda metade do XIX . A investigación centrouse nas concomitancias entre as propostas lexislativas e as obras publicadas. Ainda que tamén pescudamos aspectos biográficos máis correspondencia persoal co gallo de evidencia-la amizade e a cooperación existentes entre eles.

When we ask ourselves about a concrete definition of “Natural Capital” we can find a large and wide range of conceptions, which are attached to it. These can turn out to be confusing and contradictory in some cases. In theory, through books and different studies we know natural resources are composed by all the natural actives originated by the nature itself. Besides, these conform a patrimony for society as them are translated into a path towards economy: The Natural Capital. May not the Natural Capital be an easy conception to put in terms of economy it turns out to be an important capacitor for economy growth in most countries. In any case, we can clearly distinguish two ways as Natural Capital can be seen. One may elaborate a definition about it by reading what others have previously written, those who usually are quite far from the direct use of natural resources. On the other hand it would also be interesting to conform a definition of it by asking people who are constantly in contact with natural resources and consequently contribute to form the Natural Capital.

This paper analyses the differential impact of human capital, in terms of different levels of schooling, on regional productivity and convergence. The potential existence of geographical spillovers of human capital is also considered by applying spatial panel data techniques. The empirical analysis of Spanish provinces between 1980 and 2007 confirms the positive impact of human capital on regional productivity and convergence, but reveals no evidence of any positive geographical spillovers of human capital. In fact, in some specifications the spatial lag presented by tertiary studies has a negative effect on the variables under consideration.

El fenómeno de la inmigración está transformando las sociedades receptoras. Un creciente número de estudios revela que la reciente inmigración en España es principalmente motivada por razones económicas y por tanto se trata de una población compuesta por gente joven, cualificada y sana. Por otro lado, hay cada vez más evidencia sobre la relevancia del capital social sobre la salud. Nuestro trabajo pretende crear un puente entre la literatura sobre la inmigración y la que relaciona el capital social y la salud. El presente trabajo tiene un doble objetivo. Por un lado, queremos dilucidar la verdadera relación entre el capital social y la salud utilizando por primera vez datos de Cataluña. Por otro lado, pretendemos determinar un posible efecto diferencial del capital social sobre la salud en tres grupos de población, más concretamente, los nacidos en Cataluña, los españoles nacidos fuera de Cataluña y los inmigrantes extranjeros. Utilizamos datos de la Encuesta de Salud de Cataluña 2006, que contiene una muestra representativa del colectivo inmigrante. Los indicadores contextuales provienen de fuentes alternativas. Para determinar la relación entre el capital social y la salud (salud auto-percibida y salud mental, GHQ-12), controlando por otros factores determinantes, estimados modelos multinivel separadamente para las tres muestras poblacionales. Distinguimos entre capital social individual y capital social comunitario. Nuestros resultados revelan que el capital social individual tiene mayor impacto sobre la salud que el capital social comunitario. Sin embargo, independientemente de los indicadores de capital social empleados en el análisis, observamos que el capital social ejerce un efecto beneficioso tanto para la salud física como la salud mental en Cataluña. Además, encontramos que las redes sociales son más importantes para la salud de la población autóctona, que para la salud de los inmigrantes. Creemos que potenciar la acumulación de capital social puede ser un instrumento potencialmente eficaz (y que requiere, en comparación con otras medidas políticas, menos recursos económicos) para la consecución de los objetivos relacionados con la mejora de la salud y la reducción de las desigualdades en salud entre los colectivos de nativos e inmigrantes. Palabras clave: estado de salud, capital social, inmigración

As is known, the Kyoto Protocol proposes to reinforce national policies for emission reduction and, furthermore, to cooperate with other contracting parties. In this context, it would be necessary to assess these emissions, both in general and specifically, by pollutants and/or among productive sectors. The object of this paper is precisely to estimate the polluting emissions of industrial origin in Catalonia in the year 2001, in a multivariate context which explicitly allows a distinction to be made between the polluter and/or the productive sector causing this emission. Six pollutants considered, four directly related to greenhouse effect. A multi-level model, with two levels, pollutants and productive sectors, was specified. Both technological progress and elasticity of capital were introduced as random effects. Hence, it has been permitted that these coefficients vary according to one or other level. The most important finding in this paper is that elasticity of capital has been estimated as very non-elastic, with a range which varies between 0.162 (the paper industry) and 0.556 (commerce). In fact, and generally speaking, the greater capital the sector has, the less elasticity of capital has been estimated. Key words: Kyoto protocol, multilevel model, technological progress

L'éthicien Denis Müller présente ici une généalogie, une critique et une reconstruction théologique de l'éthique protestante. Dans un premier moment, l'auteur réfléchit à la transformation considérable qui semble affecter aujourd'hui la situation de l'éthique théologique. Dans un deuxième temps est abordée la problématique de la post-modernité dans sa dynamique de déconstruction qui affecte évidemment les modèles éthiques antérieurs. Dans une troisième partie, coeur de l'ouvrage, Denis Müller propose un modèle de reconstruction de l'éthique théologique où sont abordées des questions centrales pour toute sensibilité protestante et chrétienne: la tradition, la signification de l'herméneutique, l'usage de la Bible.
