In this paper, I try to shed some new light on the "puzzle" why the Lucas critique, belived to be important by most economists, seems to have received very little empirical support. I use a real business cycle model to examine the properties of the super exogeneity test, which is used to detect...

This paper demonstrates how a target for money growth can be beneficial for an inflation targeting central bank acting under discretion. Because the growth rate of money is closely related to the change in the interest rate and he growth of real output, delegating a money growth target to the...

Two-sided network effects in card payment systems are analysed under different market structures, e.g., competition, one-sided monopoly, bilateral monopoly and duopoly; with and without an interchange fee; for the so-called Baxter’s case of non-strategic merchants. A partial ranking of market...

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...

In this paper, I investigate quantitatively how sensitive a typical backward-looking model used in monetary plicy analysis is to the Lucas critique. To do this, I use an equilibrium business cycle model with a Taylor-type rule for nominal money growth. The backward-looking model displays...

Despite the central role of payments in theoretical and policy oriented economics, there is surprisingly little known about the costs of different payment instruments. We estimate social and private costs of cash, debit and credit card payments in Sweden in 2002. The combined social cost of...

I show that individuals whose unemployment risk tends to increase more when local home prices fall optimally invest less in owner-occupied housing. Using a unique, Swedish register based database, I find that a one standard deviation increase in the covariance between individually estimated...

We estimate the social and private costs of consumer-to-business payments in Sweden in 2009. The combined social cost for these payments was 0.68 per cent of GDP. At the point of sale, cash is socially less costly than debit cards for payments below EUR 1.88 (SEK 20) and credit cards below EUR...

We analyze the performance and robustness of some common simple rules for monetary policy in a New-Keynesian open economy model under different assumptions about the exchange rate model. Adding the exchange rate to an optimized Taylor rule gives only small improvements in terms of economic...

This paper reports and analyzes the results from a questionnaire sent to all present and former members of the Riksbank’s Executive Board, the monetary policy committee (MPC) of the Swedish central bank. The questions cover a number of issues discussed in the growing literature on monetary...
