I study a dynamic model of consumer privacy and platform data collection. In each period, consumers choose their level of platform activity. Greater activity generates more information about the consumer, thereby increasing platform profits. When the platform can commit to the future privacy...

We study competition for consumer attention, in which platforms can sacrifice service quality for attention. A platform can choose the "addictiveness" of its service. A more addictive platform yields consumers a lower utility of participation but a higher marginal utility of allocating...

A question that recent research on the global pandemic raises is: how do the assumptions underlying epidemiological models and economic models differ? Epidemiological models we now know have become quite sophisticated (see Avery et al., 2020). Debate among economic methodologists regarding the...

We introduce bounded rationality, along the lines of Gabaix (2020), in a canonical New Keynesian model calibrated to match Canadian macroeconomic data since Canada's adoption of inflation targeting. We use the model to provide a quantitative assessment of the macroeconomic impact of flexible...

In industrial applications it is quite common to use stochastic volatility models driven by semi-martingale Markov volatility processes. However, in order to fit exactly market volatilities, these models are usually extended by adding a local volatility term. Here, we consider the case of...

We propose a model of sequential spatial search with learning. There is a mapping from a space of technologies (or products) to qualities that is unknown to the searcher. The searcher can learn various points on this mapping through costly experimentation. She cares both about the technology...

Seit 2021 steigen die Energiepreise kräftig an. Mit Beginn des russischen Kriegs gegen die Ukraine sind sie noch einmal in die Höhe geschnellt. Neben Lieferkettenstörungen und Exportrückgängen dämpft das die wirtschaftliche Entwicklung, Konjunkturprognosen wurden deutlich nach unten...

We study optimal monetary policy in an analytically tractable Heterogeneous Agent New Keynesian model with rich cross-sectional heterogeneity. Optimal policy differs from that in a representative agent model because monetary policy can affect consumption inequality by reducing both idiosyncratic...

We compare sparse and dense representations of predictive models in macroeconomics, microeconomics and ftnance. To deal with a large number of possible predictors, we specify a prior that allows for both variable selection and shrinkage. The posterior distribution does not typically concentrate...

We write this essay for both lay readers and scientists, though mainstream economists are welcome to enjoy it too. Our subject is the basic toolbox of mainstream economics. The most important tools in this box are demand, supply and equilibrium. All mainstream economists – as well as many...

The object of research is a model of sustainable development of entrepreneurship in agriculture. The work considers some theoretical foundations of the process of sustainable development and characterizes the main provisions of the model of sustainable development of entrepreneurship in...

The following arguments are developed: (i) models without monetary aggregates do not imply that inflation is a non-monetary phenomenon and are not necessarily non-monetary models; (ii) theoretical considerations suggest that such models are misspecified, but the quantitative significance of this...

We compare sparse and dense representations of predictive models in macroeconomics, microeconomics and finance. To deal with a large number of possible predictors, we specify a prior that allows for both variable selection and shrinkage. The posterior distribution does not typically concentrate...

We develop a model that captures important features of debt crises of the Brazilian type. Its applicability to Brazil lies in the fact that (1) macro fundamentals were sound in the wake of the crisis (e .g., a non-negligible primary surplus, a relatively low debt/GDP ratio, low inflation, etc.);...

As a newly emerging factor, data has been widely utilized in producing goods and services, and the nonbalanced growth between digital industries and non-digital industries is significant in recent years. In the digital economy, data has two unique features. One is the fact that data in one...

When local cost discovery generates knowledge spillovers, specialization patterns become partly indeterminate and the mix of goods that a country produces may have important implications for economic growth. We demonstrate this proposition formally and adduce some empirical support for it. We...

This paper argues that detailed studies of particular economies, such as Bob Gregory%u2019s work on Australia, are relevant to all of economics. The paper builds on the concept of a model species from biology to develop the notion of a model economy %u2013 one whose experiences illuminate...

We consider the welfare effects of the emigration of workers who produce a public good (knowledge). We distinguish between the knowledge diversion and knowledge creation effects of such emigration, and show that the remaining residents of a country can gain from emigration, even when tastes for...

This paper proposes a matching model that distinguishes between job creation by existing firms and job creation by firm entrants. The paper argues that vacancy posting and job destruction on the extensive margin, i.e. from firms that enter and exit the labour market, represents a viable...

We develop a dynamic discrete choice model of training choice, employment and wage growth, allowing for job mobility, in a world where wages depend on firm-worker matches, as well as experience and tenure and jobs take time to locate. We estimate this model on a large administrative panel data...

This paper studies optimal taxation of entrepreneurial capital with private information and multiple assets. Entrepreneurial activity is subject to a dynamic moral hazard problem and entrepreneurs face idiosyncratic capital risk. We first characterize the optimal allocation subject to the...

We compare Laffer curves for labor and capital taxation for the US, the EU-14 and individual European countries, using a neoclassical growth model featuring "constant Frisch elasticity" (CFE) preferences. We provide new tax rate data. The US can increase tax revenues by 30% by raising labor...

Wealthy individuals often voluntarily provide public goods that the poor also consume. Such philanthropy is perceived as legitimizing one's wealth. Governments routinely exempt the rich from taxation on grounds of their charitable expenditure. We examine the normative logic of this exemption. We...

How do new entrants create and capture value in established industries? Starting from the foundations of neoclassical economics we model entrepreneurial entry and competition as occurring simultaneously in production technology space and product attribute space. Our model's central feature is to...

The doctrine of patent exhaustion implies that the authorized sale of patented goods “exhausts” the patent rights in the goods sold and precludes additional license fees from downstream buyers. Courts have considered absolute exhaustion, in which the patent owner forfeits all rights upon an...

In this paper, we revisit the equity premium puzzle reported in 1985 by Mehra and Prescott. We show that the large equity premium that they report can be explained by choosing a more appropriate distribution for the return data. We demonstrate that the high-risk aversion value observed by Mehra...

Agent-based models are usually claimed to generate complex dynamics; however, the link to such complexity has not been subject to rigorous examination. This paper studies this link between the complexity of financial time series---measured by their multifractal properties---and the design of...

This paper examines E-stability, determinacy, and indeterminacy in a general class of regime-switching models with lagged endogenous variables. Using determinacy conditions from Cho (2016, 2020), our first result extends McCallum (2007) to models with time-varying parameters: the unique...

Climate change is a subject that has been largely addressed from both macroeconomic and energetic standpoints. Integration of climate variables and natural capital into the traditional economic framework can appear conflicting with the notion of infinitely growing economies exploiting finite...

Tourism plays an important role in the economies of countries, which is evidenced by macroeconomic studies. However, analyses highlighted the need to do research on tourist expenditure and to identify factors at the microeconomic level. The article presents an overview of the extensively...

This paper presents Bank of Canada staff's current assessment of the US neutral rate, along with a newly developed set of models on which that assessment is based. The overall assessment is that the US neutral rate currently lies in a range of 1.75 to 2.75 percent. This represents a decline of...

We study the interaction between epidemics and economic decisions in a model where (1) agents allocate their time to market and home production and social and home leisure, (2) these activities differ in their degree of contagiousness, (3) some infected individuals are indistinguishable from...

Zahlreiche genom-editierte Kulturpflanzen stehen kurz vor ihrer Marktreife und werden daher bald ihren Weg in den internationalen Agrarhandel finden. Gegenwärtig gibt es jedoch große Unterschiede in der rechtlichen Einstufung dieser Produkte. Während beispielsweise in den USA und Brasilien...
