We argue that in an economy with downward nominal wage rigidity, the output gap is negative on average. Because it is more difficult to cut wages than to increase them, firms reduce employment more during downturns than they increase employment during expansions. This is demonstrated in a simple...

Article considers a research problem on the precise measurement of the macroeconomic variables changes in the time domain in the macroeconomics science. We propose to use the three dimensional (3D) wave diagram in the macroeconomics science for the first time, aiming to accurately characterize...

The quantum macroeconomics theory is formulated for the first time, assuming that the business cycle has the discrete-time oscillations spectrum in analogy with the electronics excitations discrete-time spectrum in the Bohr's atom model in the quantum physics. The quantum macroeconomics theory...

While conventional monetary policy maintains its role in counteracting inflation, there are doubts that it is sufficient to guard against the risks of financial instability. It has been debated whether monetary policy should lean against the wind, i.e., if central banks should also respond to...

The frequencies at which prices and wages are adjusted, interpreted as price and wage flexibility, are key elements in workhorse models used for policy analysis. Yet, there is little evidence regarding the relationship between these two sources of nominal rigidities. Using two large and highly...

The purpose of the "counter-cyclical capital buffer" (buffer) is to dampen procyclicality in the financial system, absorb capital losses and prevent a credit crunch during recessions. In this paper, a stylized analytical expression for optimal buffer policy is presented. Results are derived...

We analyse the costs and benefits of increasing capital requirements for Danish banks. Costs can be close to 0 if banks suspend dividend payments for a period of time as banks accumulate capital and if investors' required return falls. The latter implies that the Modigliani-Miller effect is...

Starting from the mid-nineteenth century, this paper analyzes two periods of financial instability connected with financial globalization. The first culminates with the 1929 crisis, while the second characterizes the more recent experience starting from the 1970s. The period in between is...

One important source of systemic risk can arise from asset commonality among financial institutions. This indirect interconnection may occur when financial institutions invest in similar or correlated assets and it is also described as overlapping portfolios. In this paper, we propose a new...

Since the mid-1990s, many OECD countries have experienced a substantial increase in household indebtedness. Sweden, in particular, has seen indebtedness rise from 90% of disposable income in 1995 to 172% in 2014. The Swedish Financial Supervisory Authority (FSA) has identified mortgage...
