| 释义 | sunspot noun[ C ] uk /ˈsʌn.spɒt/ us /ˈsʌn.spɑːt/ a dark spot on the surface of the sun that appears for a few days or weeks and then disappears太阳黑子 Stocktrek Images/GettyImages Astronomy albedo Andromeda Aquarius Aries asteroid galactic galaxy Gemini geostationary geosynchronous nova observatory orbit orbital Orion suborbital substellar supergiant supermassive supermoon Examples of sunspotsunspot However, this comes at the cost of weakening the ability of sunspot models to explain fluctuations along some dimensions. This can produce multiple equilibria and open the door to sunspot fluctuations. The examples of sunspot equilibria that were known at the time were highly stylized and involved, for example, only a finite number of random states. Indeterminacy and the sunspot do not increase these statistics and therefore do not alleviate the severity of the equity premium and other financial puzzles. In particular, we were unable to connect sunspot ideas with everyday events in financial markets, like excessive volatility in exchange rates and asset prices. Furthermore, we restrict attention to a time-invariant linear sunspot function. In this economy, agents use the sunspot signal observed at the beginning of the current period to form expectations on next-period prices only. The existence of the sunspot equilibria so defined provides a clear method for defining bubbles. Each of these is by itself a source of sunspot equilibria, but my intuition was initially driven by the double infinity and bubbles. One good friend, a distinguished macroeconomist, wrote to try to persuade me to give up sunspots on grounds of their unpopularity. One of these structures is driven by fundamentals alone; the other is driven in part by nonfundamental "sunspot" shocks. This model has become a workhorse for much of the subsequent sunspot literature. Because this value can always vary with the realization of a sunspot variable, consumption is made excessively volatile. Since sunspots change the potential payoff of the agents engaged in bargaining, they affect the final quantities traded in monetary exchanges. Our main goal is to determine the effects of local indeterminacy and the presence of sunspot shocks on asset pricing. These examples are from corpora and from sources on the web.
