Over the business cycle, labor's share of output is negatively but weakly correlated with output, and it lags output by about four quarters. Profit's share is strongly procyclical. It neither leads nor lags output, and its volatility is about four times that of output. Despite the importance of...

We study the cyclical dynamics of the value of a vacant position in labor markets characterized by search and matching frictions. We present a model of aggregate fluctuations in which firms face sunk costs to enter the production process. Our specification of sunk costs gives rise to a...

This paper constructs a theory of the coexistence of fixed-term and permanent employment contracts in an environment with ex ante identical workers and employers. Workers under fixed-term contracts can be dismissed at no cost while permanent employees enjoy labor protection. In a labor market...

Mining is one of the key features to maintain the value and the security of the Bitcoin system. Like mining of other commodities, Bitcoin mining requires a non-trivial fixed cost to enter the business. We extend a framework that captures some key features of Bitcoin to incorporate entry costs....

In order to maintain the function of a decentralized financial system like Bitcoin, transaction fees are offered to engage miners in the transaction confirmation process. This paper investigates the effect of miner competition on the equilibrium transaction fees. We develop a game-theoretic...

This paper studies the impact of higher aggregate uncertainty on labor markets where jobs with strong employment protection coexist with temporary contracts. We develop a search and matching model where firms and workers choose the type of contract. The model allows for endogenous separations...

We empirically investigate the relationship between the return on collateral and monetary policy implementation in the channel system. Recent developments in monetary theory suggest that the return on government assets which measures the opportunity cost of holding collateral should have...

In order to maintain the function of a decentralized financial system like Bitcoin, transaction fees are offered to engage miners in the transaction confirmation process. This paper investigates the effect of miner competition on the equilibrium transaction fees. We develop a game-theoretic...

We develop a general equilibrium framework to study a cryptocurrency system based on a mining process (proof-of-work protocol). The framework incorporates the priority queueing theory into a continuous-time monetary search model, which allows us to investigate the relationship between the demand...
