Theoretical Framework CPI = f( Incidence , Bias ) 				                Tax to GDP (Instrumental )   Cross Section	CPI 		  Micro Data from ICVS Equations  CPI = β0+β1ICVS + u1 ICVS(instrument) = β0 +β2Tax to GDP Ratio +u    (INSTRUMENTAL VARIBLE) CPI = β0+ β1ICVS (Instrument)+ u2 u2 – u1 = BIAS   CPI = θ 0 + θ 1 ICVS ( Inst) + θ3 Bias + u  (Have you or a Member of your family paid a gift payment to a public official in the past year)
Equation 1 (Basic CPI-ICVS Relationship) CPI = f (Incidence, Bias) 		       CPI      =     β0          +     β1 ICVS +   µ1 		       CPIest    =	   0.32	        +  2.26 ICVS (6.67)t-stat                                (5.71) t-stat 	 			    (0.0000)prob                           (0.0001) prob ε1        =     CPI        –     CPI est                   (Bias + Disturbance)        =   (Incidence + Bias)          -   ( Incidence+ Disturbance)  ε 1       =     Bias      +  Disturbance
Equation 2(Instrumental; Cleaning Disturbance/separating Bias) Instrumental variable of ICVS takes in effect of all omitted variables Tax to GDP ratio Correlated to Incidence but not to Perception  	ICVSInstrumental	=      β0		+     β1TaxtoGDP  +  µ2 	ICVSest		=     0.31	-    0.0119 TaxtoGDP 	 		        (5.50)t-stat		(-4.24) t-stat        (0.0000)prob 		(0.0001) prob
Equation 3 (Estimating Bias) 	 CPI	=	 β0	   +  β1 ICVS Instrumental + µ      CPIest	= 	0.273	   + 2.94 ICVSInstrumental (3.77)t-stat 		(4.15) t-stat                 (0.0010)prob 	(0.0000) prob ε2		= 	CPI	    -  CPIest     (Disturbance)	= ( Incidence + Bias)        –  (Incidence + Bias + Disturbance) ε2		= (Disturbance) ε1		= (Disturbance + Bias) ε1 – ε2	= BIAS
Equation 4 (Estimating Magnitude of Bias) CPI		 =	θ0       +  θ1 ICVS    +   θ2BIAS +µt  CPI		 =      029     + 2.67 ICVS +   0.4 BIAS  (5.59)t-stat 	           (5.71) t-stat	                          (1.53) t-stat                       (0.0010)prob               (0.0000) prob                   (0.1392) prob  We fail to reject Null Hypothesis
Hypothesis  Proposition There is a significant Gap Between the Incidence of Corruption and Corruption Perception Index Study Objective  To highlight if there is a  Gap between Incidence and Perception of Corruption  Hypothesis H0 : θ2 = 0  Ha :  θ2≠ 0
Data Collection Procedures  Year 2000 (Cross Sectional)  Corruption Perception Index Source : Complied by Transparency International from 14 different data Sources  Score Varies Between 0 (Corrupt) – 10 (Clean)    Inverse of CPI taken   Divided by Highest score to get values b/w 0-1  Tax to GDP Ratio  An Instrumental Variable for ICVS  Source: World Development Indicators (WDI) International Crime Victim Survey (ICVS) Source: Compiled  By UNICRI  Question used Dichotomous to Average Conversion
SAMPLE INCLUDED  United Kingdom Belgium  Canada Denmark France Netherlands Ireland Portugal Sweden  United States of America  Korea Colombia   Azerbaijan  Belarus Bulgaria  Croatia  Czech Republic  Poland  Russia Ukraine  Uganda  South Africa  Zambia  Estonia  Australia  Japan
Conclusion  Subjective Assessment  Opinion based survey vs. Reality Based Survey Survey Biases might also be present in ICVS
