Beyond the Doomsday Economics of “Proof-of-Work” in Cryptocurrencies
This paper discusses the economics of how Bitcoin achieves data immutability, and thus payment finality, via costly computations, i.e., ?proof-of-work.? Further, it explores what the future might hold for cryptocurrencies modelled on this type of consensus algorithm. The conclusions are, first, that Bitcoin counterfeiting via ?double-spending? attacks is inherently profitable, making payment finality based on proof-of-work extremely expensive. Second, the transaction market cannot generate an adequate level of ?mining? income via fees as users free-ride on the fees of other transactions in a ...

A Journal Ranking Based on Central Bank Citations
We present a ranking of journals geared toward measuring the policy relevance of research. We compute simple impact factors that count only citations made in central bank publications. Our baseline ranking focuses on the period 2014-2023 and examines all items published in the Research Papers in Economics (RePEc) database. This ranking confirms the high policy relevance of journals specializing in macro, monetary, and international economics. Also, the major general interest economic journals are represented reasonably well in this ranking. In contrast, the major finance journals fare ...

Market structure and exchange rate pass-through
In this paper, we examine the extent to which market structure and the way in which it affects pricing decisions of profit-maximizing firms can explain incomplete exchange rate pass-through. To this purpose, we evaluate how pass-through rates vary across trade partners and sectors depending on the mass and size distribution of firms affected by a particular exchange rate shock. In the first step of our analysis, we decompose bilateral exchange rate movements into broad US Dollar (USD) movements and trade-partner currency (TPC) movements. Using micro data on US import prices, we show that the ...

International liquidity provision during the financial crisis: a view from Switzerland
The authors document the provision of liquidity in Swiss francs (CHF) by the Swiss National Bank (SNB) to banks located outside Switzerland during the recent financial crisis. What makes the Swiss case special is the size of this liquidity provision?at times, 80 percent of all short-term CHF liquidity provided by the SNB?and the measures adopted to distribute this liquidity. In addition to making CHF available to other central banks via swap facilities, the SNB also allows banks outside Switzerland to directly participate in its repurchase agreement transactions. Although this policy was ...

Exchange rate pass-through in a competitive model of pricing-to-market
This paper extends the Mussa and Rosen (1978) model of quality-pricing under perfect competition. Exporters sell goods of different qualities to consumers who have heterogeneous preferences for quality. Production is subject to decreasing returns to scale and, therefore, supply and the toughness of competition react to cost changes brought about by exchange rate fluctuations. First, we predict that exchange rate shocks are imperfectly passed through into prices. Second, prices of low quality goods are more sensitive to exchange rate shocks than prices of high quality goods. Third, in response ...

The Globalisation of Inflation: the Growing Importance of Global Value Chains
Greater international economic interconnectedness over recent decades has been changing inflation dynamics. This paper presents evidence that the expansion of global value chains (GVCs), ie cross-border trade in intermediate goods and services, is an important channel through which global economic slack influences domestic inflation. In particular, we document the extent to which the growth in GVCs explains the established empirical correlation between global economic slack and national inflation rates, both across countries and over time. Accounting for the role of GVCs, we also find that ...

Embedded Supervision: How to Build Regulation into Blockchain Finance
The spread of distributed ledger technology (DLT) in finance could help to improve the efficiency and quality of supervision. This paper makes the case for embedded supervision, i.e., a regulatory framework that provides for compliance in tokenized markets to be automatically monitored by reading the market?s ledger, thus reducing the need for firms to actively collect, verify and deliver data. After sketching out a design for such schemes, the paper explores the conditions under which distributed ledger data might be used to monitor compliance. To this end, a decentralized market is modelled ...

Exchange rate pass-through, domestic competition and inflation -- evidence from the 2005/08 revaluation of the Renminbi
How important is the effect of exchange rate fluctuations on the competitive environment faced by domestic firms and the prices they charge? To answer this question, this paper examines the 17 percent appreciation of the yuan against the U.S. dollar from 2005 to 2008. In a monthly panel covering 110 sectors, a 1 percent appreciation of the Yuan increases U.S. import prices by roughly 0.8 percent. It is then shown that import prices, in turn, pass through into producer prices at an average rate of roughly 0.7, implying that a 1 percent Yuan appreciation increases the average U.S. producer ...

A journal ranking based on central bank citations
We present a ranking of journals geared toward measuring the policy relevance of research. We compute simple impact factors that count only citations made in central bank publications, such as their working paper series. Whereas this ranking confirms the policy relevance of the major general interest journals in the field of economics, the major finance journals fare less favourably. Journals specialising in monetary economics, international economics and financial intermediation feature highly, but surprisingly not those specialising in econometrics. The ranking is topped by the Brookings ...
