R&D investment has well-known liquidity problems, with potentially important consequences. In this paper, we analyze the effects of monetary policy on economic growth and social welfare in a Schumpeterian model with cash-in-advance (CIA) constraints on consumption, R&D investment, and...

In this paper we develop a model where agents can acquire goods using cash and two non-cash alternatives. We use it to study the effects of the pricing policy of payment methods implemented in Norway, carried out by individual banks and promoted by the authorities. We show that this policy...

R&D investment has well-known liquidity problems, with potentially important consequences. In this paper, we analyze the effects of monetary policy on economic growth and social welfare in a Schumpeterian model with cash-in-advance (CIA) constraints on consumption, R&D investment, and...

The possibility of indeterminacy and sunspot fluctuations in dynamic rational expectations models has been often questioned on empirical grounds, for such models are widely believed to rely on implausibly high degrees of increasing returns to scale and/or other controversial calibrations of...

The goal of this study is to determine the reasons behind high cash demand in several Central European countries, especially Hungary. We distinguish between legal and illegal cash demand in an attempt to model the former. In our approach, legal cash demand can be explained by transactional and...

This comment provides a reply to Prof. Feige’s paper with the title “Reflections on the Meaning and Measurement of Unobserved Economies: What do we really know about the ‘Shadow Economy’?”, in which Prof. Feige heavily criticizes me. I show that the same critique which Prof. Feige...

Cash payments are simple, secure, efficient and anonymous and therefore popular with consumers. At the same time, these properties also make cash a focal point for potential illegal uses. An oft-voiced opinion in the public debate is that cash promotes the shadow economy and is used as a means...

Over millennia, mankind has used hard cash in various forms ranging from shells to gold coins and paper. More recently, cash has become unpopular in political circles, as it effectively restricts states’ power to tax (explicitly or via negative interest rates) or to survey and potentially...

We use an 'unexplained demand for cash' approach to measure the size of the shadow economy in Sweden. The size of the shadow economy is found to have increased from 3.8 to 6.5 per cent of GDP from 1990 to 2004. This result is also supported by our finding of an increased residual between...
