Constructs and Variables in Research

 

 

Understanding constructs and variables is essential in designing sound research, especially in social sciences, psychology, and finance. These two elements form the building blocks of any research study.

 1. Constructs

 Definition:

A construct is an abstract concept or theoretical idea that is not directly observable but can be measured using indicators or variables.

 Characteristics:

·         Intangible and conceptual

·         Must be operationally defined before measurement

·         Used to build theories and hypotheses

 Examples in Finance:

Construct

Description

Financial Literacy

A person’s understanding of financial concepts and tools

Risk Tolerance

Willingness to take financial risks in investments

Investor Confidence

Belief in one’s ability to make sound investment decisions

Job Satisfaction

Level of contentment with financial job roles or pay

Perceived Value

A consumer’s subjective valuation of financial products

 2. Variables

Definition:

A variable is a measurable representation of a construct. It is any factor or characteristic that can vary across individuals or situations.

 Types of Variables:

Type of Variable

Description

Example (Finance Context)

Independent Variable (IV)

The cause or factor manipulated or categorized to see its effect

Financial literacy training (Yes/No)

Dependent Variable (DV)

The outcome or effect being measured

Monthly savings, investment amount

Control Variable

Factors kept constant to prevent interference

Age, income level, education

Moderating Variable

Affects the strength or direction of the IV-DV relationship

Risk tolerance moderates the effect of income on investment

Mediating Variable

Explains the mechanism between IV and DV

Financial attitude mediates between literacy and investment behavior

 Relationship Between Constructs and Variables

Component

Example from Finance Research

Construct

Financial Literacy

Operational Definition

Score on a standardized financial knowledge test

Variable

Financial Literacy Score (ranging from 0 to 100)

 Example: From Construct to Variable in Finance Research

Research Question:

Does financial literacy improve retirement planning among working professionals?

Element

Example

Construct 1

Financial Literacy

Variable 1 (IV)

Financial literacy score (measured through a quiz)

Construct 2

Retirement Planning

Variable 2 (DV)

Number of retirement instruments used (NPS, EPF, PPF)

 Summary Table

Term

Description

Example

Construct

Abstract concept needing definition

Risk attitude, investment confidence

Variable

Measurable attribute representing the construct

Risk score (1 to 10), confidence scale

IV

The influencing factor

Literacy training

DV

The outcome being studied

Monthly investment amount

Two-Step System GMM (Generalized Method of Moments)

 The Two-Step System GMM is a dynamic panel data estimation technique designed to address: Endogeneity of explanatory variables Unobserved heterogeneity (fixed effects) Autocorrelation and heteroskedasticity It improves upon simpler estimators (like OLS or FE) and is particularly useful when the model includes lagged dependent variables . ⚙️ System GMM: The Basics Developed by Arellano & Bover (1995) and Blundell & Bond (1998) , System GMM combines: Difference GMM (Arellano & Bond, 1991): First-differences the model to remove fixed effects and uses lagged levels as instruments . Level GMM (Blundell & Bond) : Uses lagged differences as instruments for the level equation to improve efficiency. 🧮 The Dynamic Panel Model A typical dynamic panel data model is: y i t = α y i t − 1 + β X i t + μ i + ε i t y_{it} = \alpha y_{it-1} + \beta X_{it} + \mu_i + \varepsilon_{it} y i t ​ = α y i t − 1 ​ + β X i t ​ + μ i ​ + ε i t ​ Where: y...

Shodhganaga vs Shodhgangotri

  Shodhganga and Shodhgangotri are both initiatives by the INFLIBNET Centre (Information and Library Network Centre) in India. They aim to promote research and knowledge sharing in the academic community but serve different purposes. Here’s a comparison: Feature Shodhganga Shodhgangotri Purpose Repository for completed theses and dissertations. Repository for research proposals and synopses. Content Full-text doctoral theses and dissertations submitted by universities. Approved research proposals and synopses of doctoral students. Focus Stage of Research Final stage – after the research is completed. Initial stage – before the research begins. Target Audience Researchers looking for completed, peer-reviewed research work. Scholars looking for examples or ideas for research topics and methodologies. Utility ...

Panel Stationarity Tests: CADF and CIPS Explained

 When dealing with panel data , testing for stationarity (i.e., whether variables have a constant mean and variance over time) is crucial before estimation—especially in macroeconomic and financial studies. Two advanced second-generation panel unit root tests used to check for stationarity while accounting for cross-sectional dependence are: 🔹 1. CADF (Cross-sectionally Augmented Dickey-Fuller) Test 📌 Developed by: Pesaran (2007) CADF is an extension of the Augmented Dickey-Fuller (ADF) test that augments each ADF regression with cross-sectional averages to account for cross-sectional dependence . 🔍 Model Form: For each unit i i i , the CADF regression is: Δ y i t = a i + b i y i , t − 1 + c i y ˉ t − 1 + d i Δ y ˉ t + ∑ j = 1 p ϕ i j Δ y i , t − j + ε i t \Delta y_{it} = a_i + b_i y_{i,t-1} + c_i \bar{y}_{t-1} + d_i \Delta \bar{y}_{t} + \sum_{j=1}^{p} \phi_{ij} \Delta y_{i,t-j} + \varepsilon_{it} Δ y i t ​ = a i ​ + b i ​ y i , t − 1 ​ + c i ​ y ˉ ​ t − 1 ​ + d i ...
