Towards a theory of platform dynamics

I introduce a dynamic framework to analyze platforms. The (single) platform owner sets prices at the beginning of each period. Agents (buyers, sellers, readers, consumers, merchants, etc.) make platform membership decisions occasionally. I show that an optimal platform pricing addresses two externalities: across sides and across time periods. This results in optimal prices which depend on platform size in a nontrivial way. By means of numerical simulations, I examine the determinants of equilibrium platform size, showing that the stationary distribution of platform size may be bimodal, that is, with some probability the platform remains very low or takes very long to increase in size. I also contrast the dynamics of proprietary versus nonproprietary (i.e., zero‐priced) platforms, and consider the specific case of asymmetric platforms (one side cares about the other but not vice versa).     

Low skill wages and mismeasured inflation

The current literature presents evidence that the real wage of male workers at the 10th percentile of the wage distribution has fallen since 1970. Yet, contributions within this literature deflate nominal wages using a mismeasured deflator. Another strand of literature documents that the mismeasurement of the deflator is sizable, with recent estimates exceeding0.6 percentage points per year. In this paper, I adjust the deflator and reestimate the implied evolution of male low skill wages. This simple exercise implies that male low skill wages were about 15 log-points higher in 2013 than in 1970.     

Constructing an entrepreneurial life: liminality and emotional reflexivity in identity work

ABSTRACT

This paper examines the identity work of a budding entrepreneur through a longitudinal case study based on his ongoing personal reflections as he tries to construct an entrepreneurial life. In particular, we investigate the role of emotional reflexivity and liminality, concepts that give us analytical purchase in exploring the complex dynamics of this identity work. The liminal condition of multiple identity positions enables our informant to experiment with and integrate several parallel identity narratives as he tries on socio-political constructions of ‘the entrepreneur’ for size; and it is the permanence of the liminal condition that makes emotional reflexivity necessary so he can handle the constant lack he experiences. The contribution of our work lies in exploring how the operation of the discourse of enterprise never closes on the centre of subjectivity that is imputed in that discourse, and how our subject, through emotional reflexivity, deals with this fundamental lack.     

Assessing the impact of individual and context factors on the entrepreneurial process. A cross-country multilevel approach

This paper attempts to fill the gap on the existing entrepreneurship literature by empirically testing the influence of two groups of individual-level factors (socio-economic, demographic and perceptual characteristics) and two groups of country-level factors (both formal and informal institutional measures and macroeconomic variables) on three stages of the entrepreneurial process. We analyze the interplay between individual and context factors in nascent, young and established entrepreneurs across 49 different countries, mixing data from different sources and applying multilevel binary logistic regression models. Our results show that entrepreneurial activities are male headed, irrespectively of the entrepreneurial stage of their activities, and that highly-educated entrepreneurs are more oriented to start up new ventures. The existence of a wider network of people involved in entrepreneurship contributes to updating information on new markets and opportunities, leading to a more accurate entrepreneurial decision. The level of development of a country constitutes an important determinant of entrepreneurship but also moderates the relationship between entrepreneurship and institutional factors. In more developed countries, individual characteristics may be still determinant factors shaping the decision to become an entrepreneur, although their magnitude may depend on the stage of the entrepreneurial process. Finally, the key to entrepreneurship for both more and less developed countries seems to be their fiscal systems: a fair tax system that actively fights tax evasion and corruption seems to be essential to reducing the economic pressure associated with the creation and survival of ventures.

     

When Borch's Theorem Does Not Apply: Some Key Implications of Market Incompleteness,with Policy Relevance Today

Markets are incomplete when the assets available to the agents do not span the space of future contingencies. In that case, competitive equilibria on the markets for assets and commodities fail (generically) to be constrained efficient. Pareto‐superior allocations can be implemented through price/wage rigidities and quantity constraints. However, nominal rigidities are conducive to multiple equilibria, implying endogenous macroeconomic uncertainties that compound the primitive (exogenous) uncertainties. This paper defines a temporary general equilibrium for which there exists a set of equilibria defining an inflation – unemployment locus. Various policy implications are drawn, with relevance to the current crisis.

Crecimiento económico,flexibilización laboral y calidad del empleo en Colombia de 2002 a 2011

Tras analizar el mercado de trabajo colombiano entre 2002 y 2011, los autores constatan una mejora sustancial de las oportunidades de empleo, junto con el aumento del empleo atípico. Exploran cómo ello afectó a la calidad del empleo mediante un indicador compuesto basado en el método de componentes principales categóricos, y concluyen que hubo una leve mejora generalizada, debida al aumento de los ingresos y de la seguridad social y al menor subempleo por horas, que benefició sobre todo a las trabajadoras independientes. Ello deja todavía un déficit cualitativo importante, que requiere políticas de estímulo de la institucionalidad y la productividad laborales y de la inversión.     

Electoral fraud, the rise of Peron and demise of checks and balances in Argentina

The future looked bright for Argentina in the early twentieth century. It had already achieved high levels of income per capita and was moving away from authoritarian government towards a more open democracy. Unfortunately, Argentina never finished the transition. The turning point occurred in the 1930s when to stay in power, the Conservatives in the Pampas resorted to electoral fraud, which neither the legislative, executive, or judicial branches checked. The decade of unchecked electoral fraud led to the support for Juan Peron and subsequently to political and economic instability.
