A Note on Credit Allocation,Income Distribution and the Circuit of Capital

This note considers the relationship between credit allocation and the class distribution of income in the Circuit of Capital. Production and consumption credit inject means of purchase into different phases of capitalist reproduction. Comparative‐dynamic analysis of steady‐state evolutions shows that in the dynamic terms of Circuit of Capital production and consumption credit respectively increase wage and profit shares of aggregate income. These findings hold more broadly for any setting where sectoral revenue elasticities of outlays are below unity. They also have direct policy relevance for advanced and middle‐income economies where household borrowing has been encouraged in attempts to support demand and growth.     

A systemic approach to modelling and estimating demand for money(ies)

This article uses a consumer theory-based systemic approach to model the demand for monetary liquid asset holdings in Chile. We implement the suggestions and caveats of aggregation theory for the estimation of a demand system for liquid assets (monies) in static, dynamic and time-varying parameters setups. Our results are robust and theoretically consistent with consumer theory restrictions, as a system derived from a utility maximizing framework and a quasi concave utility function. In our estimations, we find stability of interest rate elasticities, in contrast to previous related literature. We also document evidence that long (short) maturity rates are associated to less (more) liquid assets.     

Identifying vertically differentiated products

Rauch (1999) introduced a product classification scheme that has since been widely used to empirically identify differentiated goods. Using firm-level data on export unit values, we provide direct evidence that this classification is well suited for capturing quality differentiation.     

Globalization,product differentiation,and wage inequality

Abstract This paper develops a two‐country, general equilibrium model of oligopoly in which the degree of horizontal product differentiation is endogenously determined by firms’ strategic investments in product innovation. Consumers seek variety and product innovation is more skill intensive than production. Stronger import competition increases innovation incentives, and thereby the relative demand for skill. An intra‐industry trade expansion following trade liberalization can therefore increase wage inequality between skilled and unskilled workers. As long as some industries remain shielded from international competition, the welfare implications of globalization are found to be generally ambiguous.     

Digging out the PPP hypothesis: an integrated empirical coverage

We use several popular tests to test the validity of the Purchasing Power Parity (PPP) hypothesis. In particular, we analyze four classes of tests??standard univariate unit root tests, co-integration, panel unit root tests, and unit root tests for nonlinear frameworks??for a dataset consisting of 20 bilateral exchange rates. Through this approach, we ascertain the effectiveness of each methodology in assessing the validity of PPP. Overall, our results suggest little evidence to support PPP. Among the conducted tests, the Panel Analysis of Nonstationarity in the Idiosyncratic and Common components (PANIC) provides the richest insights by disentangling the possible sources of non-stationarity of real exchange rates. The relevance of using price indices with different characteristics is also pinpointed.     

License to till: The privileges of the Spanish Mesta as a case of second-best institutions

The Mesta was the association of the migratory shepherds of Castile, controlling fine wool production between the thirteenth and the nineteenth centuries. Its royally granted privileges have often been blamed for the stagnant Spanish agricultural productivity during the early modern period. I argue that the Mesta’s privileges allowed Medieval Castile to develop its comparative advantage in wool, and that the Crown was able to restrict their scope and application when economic conditions favored arable farming interests. I support my argument with extensive archival data, including a new series of wool prices and a detailed analysis of lawsuits involving the Mesta.     

Making real options work for practitioners: a generic model for valuing R&D projects

We propose a generic valuation framework for the appraisal of R&D projects based on real option theory. The added value of this approach is the presentation of a model that was implemented in a manner that allows corporate decision makers to use real options in an intuitive and standardized way. The project valuation procedure is separated into three main phases: project modeling, data and input collection, and result generation and analysis. The project model represents the structure of the real world R&D project with its investments, expected results, and decisions that need to be taken conditionally on the outcomes of research activities. The project model is represented in the form of a decision tree, where different research results or taken decisions lead to new branches. In this way, every possible situation the project can pass through can be represented. Uncertainties are separated into market uncertainties (e.g., market prices) and project specific, private uncertainties (e.g. uncertainty of research results). For both uncertainties, event trees are constructed which are then combined and merged with the above mentioned decision tree in order to represent the value evolution of the R&D project under given decisions and uncertainties. For every possible state of the project the real option value is calculated. By creating multidimensional trees, a multitude of decision steps and various kinds of real options (e.g., continue, expansion, switch, abandonment) can be modeled. The calculation complexity for the decision trees is given. From the tree structure we can calculate the real option value of starting an R&D project, i.e., the value of undertaking the first investment and thus acquiring the subsequent decision opportunities given by the completion of the first research effort. Furthermore, the optimal exercise strategy is derived from the decision tree. The exercise strategy gives the manager the possibility to have an a priori overview of where an R&D project may lead to, which decisions need to be taken in which circumstances, and when the project needs to be stopped in order not to generate losses. In an in‐depth case study we use an illustrative R&D project to set up and discuss the three phases of project modeling in the real options framework: building the multidimensional decision tree, input generation, and calculation of the real option value as well as the optimal strategy for the R&D project.     

Corruption and auctions

We investigate how corruption affects the outcome of a first-price auction (bidding behavior, efficiency and the seller’s expected revenue). The auctioneer approaches the winner to offer the possibility of a reduction in his bid in exchange for a bribe. The bribe can be a percentage of the difference between the winning and the second-highest bid or a fixed amount. We show that there exists a symmetric bidding strategy equilibrium that is monotone, i.e., higher valuation buyers bid higher. Corruption does not affect efficiency but both the auctioneer’s expected bribe and the seller’s expected revenue depend on the format of the bribe payments. We also find the optimal bribe scheme.
