Econometric analysis of linearized singular dynamic stochastic general equilibrium models

In this paper I propose an alternative to calibration of linearized singular dynamic stochastic general equilibrium models. Given an a-theoretical econometric model as a representative of the data generating process, I will construct an information measure which compares the conditional distribution of the econometric model variables with the corresponding singular conditional distribution of the theoretical model variables. The singularity problem will be solved by using convolutions of both distributions with a non-singular distribution. This information measure will then be maximized to the deep parameters of the theoretical model, which links these parameters to the parameters of the econometric model and provides an alternative to calibration. This approach will be illustrated by an application to a linearized version of the stochastic growth model of King, Plosser and Rebelo.     

Is Private Saving in Latin America and the Caribbean Different?

Private saving and economic growth are intimately linked, and low saving rates in Latin America and the Caribbean (LAC) have often been held responsible for disappointing growth in the region. Thus, identifying factors that spur saving is critical. This paper surveys previous empirical studies on LAC, highlighting contradictions, omissions and in some cases inconclusiveness of findings. Relying on a large dataset and a nested econometric framework, it analyzes private saving patterns and explores the role of its determinants in LAC, across LAC sub‐regions and compared with other regions. While the results highlight great heterogeneity in private saving rates within LAC and compared with the rest of the world, saving determinants are broadly the same notwithstanding some differences in sensitivity and contributions' sizes, and include its lag, income, demographics and public saving.     

Assessing the impact of patent infringement on new product sales

In order to assess the impact of patent infringement on the growth of a new product, a model is developed through the intervention model development processes of Box-Jenkins and Box-Tiao. Physical interpretations of model parameters and determination of associated damages suggest that the model can provide a sound basis for analyzing patent infringement disputes.     

A Note on Capital IQ's Credit Line Data

Empirical work in finance is increasingly using Capital IQ's detailed data on capital structure. We compare the Capital IQ credit line data to hand‐collected data for a random sample of firms. Missing values in Capital IQ are prevalent, so the data set underreports the importance of corporate credit lines. When data are reported, Capital IQ often differs from hand‐collected credit line activity. We suggest methods for correcting the errors in the Capital IQ data, note which portions of the data are most reliable, and quantify the effects of Capital IQ's underreporting by examining the tradeoff between cash and lines of credit.     

Living Labs as an Approach to Strengthen Agricultural Knowledge and Innovation Systems

Climate and ecosystem changes, economic and policy imperatives, food system pressures, and multiple societal expectations pose complex challenges for sustainable farming. A key problem is determining an effective and efficient approach to enable innovation in complex, multi-stakeholder settings. One approach currently receiving much policy attention and investment in the EU is ‘Living Labs’ which bring together public and private stakeholders to co-create, validate, and test new services, business ideas, markets and technologies. However, the analysis, monitoring and evaluation of Living Labs and their effectiveness and policy value in different contexts is limited. The AgriLink Living Labs were undertaken between 2018 and 2021 in Italy, Latvia, The Netherlands, Norway, Romania and Spain to co-create innovation support for improving agricultural sustainability. Our evaluation suggests that four inter-related critical conditions are needed for the success of Living Labs. These relate to the complexity of the challenge, the enabling environment, the proficient facilitation and the energy to move. These conditions influence the functioning of the Living Lab and we discuss the implications for policymakers and practitioners for the deployment of Living Labs in agricultural settings.     

Burn or bury? A social cost comparison of final waste disposal methods

This paper evaluates the two well-known final waste disposal methods, incineration and landfilling. In particular we compare the social cost of two best-available technologies using a point estimate based on private and environmental cost data for the Netherlands. Not only does our comparison allow for Waste-to-Energy incineration plants but for landfills as well. The data provide support for the widespread policy preference for incineration over landfilling only if the analysis is restricted to environmental costs alone and includes savings of both energy and material recovery. Gross private costs, however, are so much higher for incineration, that landfilling is the social cost minimizing option at the margin even in a densely populated country such as the Netherlands. Furthermore, we show that our result generalizes to other European countries and probably to the USA. Implications for waste policy are discussed as well. Proper treatment of and energy recovery from landfills seem to be the most important targets for waste policy. Finally, WTE plants are a very expensive way to save on climate change emissions.     

Semi-nonparametric estimation of independently and identically repeated first-price auctions via an integrated simulated moments method

In this paper we propose to estimate the value distribution of independently and identically repeated first-price auctions directly via a semi-nonparametric integrated simulated moments sieve approach. Given a candidate value distribution function in a sieve space, we simulate bids according to the equilibrium bid function involved. We take the difference of the empirical characteristic functions of the actual and simulated bids as the moment function. The objective function is then the integral of the squared moment function over an interval. Minimizing this integral to the distribution functions in the sieve space involved and letting the sieve order increase to infinity with the sample size then yields a uniformly consistent semi-nonparametric estimator of the actual value distribution. Also, we propose an integrated moment test for the validity of the first-price auction model, and an data-driven method for the choice of the sieve order. Finally, we conduct a few numerical experiments to check the performance of our approach.     

Inequality in turbulent times: income distribution in Germany and Britain, 1900–50

Using social tables, this article provides new data on inequality in Germany and Britain on an annual basis for the first half of the twentieth century. Inequality trends in these two countries tended to follow opposite patterns. The decline in inequality in Germany was interrupted during the First World War and the Nazi period, while in Britain the reversal took place between the end of the First World War and the Great Depression. Results show that the drop in inequality during the twentieth century in Europe did not follow secular trends, thus supporting the notion of inequality cycles.
