Real business-cycle theory (RBC theory) is a class of new classical macroeconomics models in which business-cycle fluctuations are accounted for by real (in contrast to nominal) shocks. [1] Unlike other leading theories of the business cycle, [ citation needed ] RBC theory sees business cycle fluctuations as the efficient response to exogenous ...
In probability theory, the coupon collector's problem refers to mathematical analysis of "collect all coupons and win" contests. It asks the following question: if each box of a given product (e.g., breakfast cereals) contains a coupon, and there are n different types of coupons, what is the probability that more than t boxes need to be bought ...
10 year minus 2 year treasury yield. In finance, the yield curve is a graph which depicts how the yields on debt instruments – such as bonds – vary as a function of their years remaining to maturity. [ 1][ 2] Typically, the graph's horizontal or x-axis is a time line of months or years remaining to maturity, with the shortest maturity on ...
the Receivables conversion period (or "Days sales outstanding") emerges as interval B→D (i.e.being owed cash→collecting cash) Knowledge of any three of these conversion cycles permits derivation of the fourth (leaving aside the operating cycle, which is just the sum of the inventory conversion period and the receivables conversion period ...
t. e. Business cycles are intervals of general expansion followed by recession in economic performance. The changes in economic activity that characterize business cycles have important implications for the welfare of the general population, government institutions, and private sector firms. There are numerous specific definitions of what ...
Cobweb model. The cobweb model or cobweb theory is an economic model that explains why prices may be subjected to periodic fluctuations in certain types of markets. It describes cyclical supply and demand in a market where the amount produced must be chosen before prices are observed.
In dynamical systems theory, a period-doubling bifurcation occurs when a slight change in a system's parameters causes a new periodic trajectory to emerge from an existing periodic trajectory—the new one having double the period of the original. With the doubled period, it takes twice as long (or, in a discrete dynamical system, twice as many ...
Bifurcation diagram. In mathematics, particularly in dynamical systems, a bifurcation diagram shows the values visited or approached asymptotically (fixed points, periodic orbits, or chaotic attractors) of a system as a function of a bifurcation parameter in the system. [citation needed] It is usual to represent stable values with a solid line ...
