CME 1 Flashcards
Business Cycle
Fluctuations in GDP in relation to longterm trend growth, usually 9-11 years
Capital markets expectations
Risk/return prospects of asset classes
Cross-sectional consistency
A feature for expectations setting that says:
Estimates for all asset classes:
(i) same underlying assumptions
(ii) key relationships maintained (e.g., strong correlations)
Internal consistency across asset classes
Diffusion index
Number of up/down indicators
Econometrics
Application of
(i) QUANT modeling
(ii) ECON theory analysis
to
analysis of economic DATA
Economic indicators
Econ stats on:
(i) economy’s recent past activity
(ii) current or future position in business cycle
Provide by:
(i) government
(ii) established private organizations
Intertemporal consistency
A feature of expectations setting
Estimates for an asset class over different horizons reflect same assumptions re potential paths of returns over time.
Internal consistency over time horizons.
Leading indicators
Econ variables whose values vary w/ business cycle but at a fairly consistent time internal b/f a turn in the cycle.
Model uncertainty
Ditto
Nonstationarity
Series properties (µ, σ) not consistent through time
Parameter uncertainty
Uncertainty arising b/c quant model’s parameters are estimated w/ error.
Re-base
Changing base time period of an index
Reduced-form models
Models using econ theory and other factors (e.g., prior research output) to describe hypothesized relationships.
More compact representations of underlying structural models.
Evaluate endogenous variables in terms of observable exogenous variables.
Regime
Governing set of relationships (b/t variables) that stem from various environmental/policy factors:
(i) technological
(ii) political
(iii) legal
(iv) regulatory
Changes in such factors are changes in regime.
Structural models
Specify functional relationships among variables based on econ theory.
The functional form and parameters of these models derived from underlying theory.
May include unobservable parameters.
