This study theoretically considers household behavior with wealth preference and empirically investigates the validity of insatiable wealth preference using a nationally representative survey. With wealth preference, the marginal rate of substitution of asset holdings for consumption depends on...

In economics and finance, speculative bubbles take the form of locally explosive dynamics that eventually collapse. We propose a test for the presence of speculative bubbles in the context of mixed causal-noncausal autoregressive processes. The test exploits the fact that bubbles are...

This paper examines how monetary expansion causes asset bubbles. When there is no monetary expansion, a bubbly asset is not created due to a hold-up problem. Monetary expansion increases buyers' money holdings, and then, dealers are willing to buy a worthless asset from sellers, in hopes of...

The stock market operates on informed decisions based on information gathered from heterogeneous sources, encompassing diverse beliefs, strategies, and knowledge. This study examines the validity of rational bubbles in stock market prices, focusing on eight African stock markets: South Africa,...

The over-hyped Dot.com revolution bubbled and crashed at the end of the 1990s, leaving a largely unused physical and virtual infrastructure that eventually supported the rise of social media that did-indeed-transform life. Not necessarily in a good way. As Robert Gordon famously claimed, you can...

This paper investigates the presence and timing of explosive price dynamics in major listed real estate markets over the period 04 January 2011 - 11 February 2026. The analysis focuses on four benchmark indices: the FTSE EPRA Nareit Developed Europe Index, the FTSE Nareit All Equity REITs Index...

The global financial crisis (2008-2009) represents a notable example of a generally unpredicted crisis in economic history. Nevertheless, it presented features comparable to almost any previous (monetarily related) crisis episode. For instance, it was characterized by a "vicious cycle" made by...

Galí (2014) showed that a monetary policy rule that raises interest rates in response to bubbles can paradoxically lead to larger bubbles. This comment shows that a central bank that wants to dampen bubbles can always do so by raising interest rates aggressively enough. This result is different...

This paper proposes concepts and methods to investigate whether the bubble patterns observed in individual time series are common among them. Having established the conditions under which common bubbles are present within the class of mixed causal-noncausal vector autoregressive models, we...

While there is a large body of literature on oil uncertainty-equity prices and/or returns nexus, an associated important question of how oil market uncertainty affects stock market bubbles remains unanswered. In this paper, we first use the Multi-Scale Log-Periodic Power Law Singularity...

Financial bubbles and crashes have repeatedly caused economic turmoil notably but not only during the 2008 financial crisis. However, both in the popular press as well as scientific publications, the meaning of bubble is sometimes unspecified. Due to the multitude of bubble definitions, we...

Queen Anne's Bounty was a corporation created in 1704 to redistribute income within the Anglican clergy. Structurally a saver needing a liquid asset, the corporation pursued a conservative strategy of investing in the dominant form of government debt, adapting as the market changed. It was...

Britain's debt was nil in 1688 and 60% of GDP in 1717. From 1717 to 1722 the debt was restructured, including through the South Sea operation of 1720. I discuss the reasons for the restructuring and the tensions it revealed between taxpayers and creditors. The South Sea bubble turned the...
